SSM 整合

  整合的思路是：

   先创建spring框架

   通过spring整合spring mvc

   通过spring整合mybatis

工程创建

   创建Maven工程–>create for archtype–>webapp

创建项目结构

  在recourses目录下创建 dbconfig.properties,log4j.properties,mysqlConfig.xml,springmvc.xml,applicationContext.xml

工作流程

在pom.xml添加相关依赖 — mybatis

基本思路

建立spring框架

1.创建bean

代码语言：javascript复制
public class user implements Serializable {
    private Integer id;
    private String name;
    private String gender;
    private String email;
    @Override
    public String toString() {
        return "user{"  
                "id="   id  
                ", name='"   name   '''  
                ", gender='"   gender   '''  
                ", email='"   email   '''  
                '}';
    }
    
    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

2.创建bean的dao

代码语言：javascript复制
public interface userDao {
    public List<user> findAll();
}

3.创建bean的userService的接口

代码语言：javascript复制
package club.twzw.service;

import club.twzw.bean.User;
import org.springframework.stereotype.Service;

import java.util.List;

public interface UserService {
    public List<User> findAll();

}

4.实现userServiceImpl,并给userServiceImpl 起别名userService

代码语言：javascript复制
@Service("userService")					<<<<-----------
public class userServiceImpl implements userService {
    
    @Override
    public List<user> findAll() {
        System.out.println("查询所有用户。。。");
        return null;//service.findAll();
    }
}

5.在resources文件下创建文件applicationContext.xml

代码语言：javascript复制
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">


    <!--只处理Service和dao -->
    <context:component-scan base-package="club.twzw">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
	
</beans>

7.书写测试方法

代码语言：javascript复制
    @Test
    public void testQueryUserList() {
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        userService service = (userService) ac.getBean("userService"); // 因为给service起了别名，所以通过id的方式获取class
        service.findAll();

    }

输出

至此spring框架已经创建。

建立spring mvc

在web.xml文件中修改并配置过滤器，中文乱码过滤

代码语言：javascript复制
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
  
    <servlet>
        <servlet-name>spring-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--加载springmvc.xml配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!--启动服务器时，创建该servlet-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--配置中文乱码过滤器-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/</url-pattern>
    </filter-mapping>
</web-app>

在resources文件夹下创建springmvc.xml文件,开启注解扫描，视图解析器以及过滤静态资源和springmvc注解支持

代码语言：javascript复制
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--开启注解扫描，只扫描controller-->
    <context:component-scan base-package="club.twzw">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--配置视图解析器-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="suffix" value=".jsp"/>
        <property name="prefix" value="/WEB-INF/views/"/>
    </bean>

    <!--过滤静态资源-->
    <!--    <mvc:resources mapping="/css/**" location="/css/"/>-->
    <!--    <mvc:resources mapping="/images/**" location="/images/"/>-->
    <!--    <mvc:resources mapping="/js/**" location="/js/"/>-->


    <!--开启springmvc注解支持-->
    <mvc:annotation-driven/>

</beans>

书写controller

代码语言：javascript复制
package club.twzw.controller;

import club.twzw.bean.User;
import club.twzw.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
public class UserController {

    @Autowired
    private UserService service;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("success");
        List<User> all = service.findAll();
        model.addAttribute("user",all);
        return "list";
    }
}

index.jsp

代码语言：javascript复制
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
	<body>
		<a href="/findAll">查看所有用户</a>
	</body>
</html>

success.jsp

代码语言：javascript复制
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
	<head>
    	<title>scuccess</title>
	</head>
	<body>
    	<h1>scuccess</h1>
	</body>
</html>

页面如果做成显示，自此成功添加spring mvc 开始整合

在整合之前需要明白，我们需要在controller中调用service，最快捷的便是使用依赖注入，而至今使用Tomcat服务器只加载了springmvc.xml文件，并没有applicationContext.xml的加载（也就是spring并没有被加载），所以可以通过监听ServeltContext域对象，在创建时加载spring的配置文件（applicationContext.xml）

配置监听器

在web.xml文件下添加listener,context-param设置监听和applicationContext.xml的文件路径

代码语言：javascript复制
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <!--加载Spring-->
    <!--配置监听器,默认只加载web-inf目录下的applicationContext.xml-->
    <!--但是我们的文件在resources文件夹下-->    					<<<<------
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!--设置配置文件路径-->											<<<<------
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <!--加载spring mvc-->
    <!--配置前端控制器-->
    <servlet>
        <servlet-name>spring-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--加载springmvc.xml配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!--启动服务器时，创建该servlet-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--配置中文乱码过滤器-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/</url-pattern>
    </filter-mapping>
</web-app>

这样我们就可以使用依赖注入了

使用依赖注入并从新发布,如果正常，就可以在控制台看到两句话

代码语言：javascript复制
package club.twzw.controller;
import club.twzw.service.impl.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class UserController {

    @Autowired
    private UserService service;

    @RequestMapping("/findAll")
    public String findAll(){
        System.out.println("success");
        service.findAll();
        return "success";
    }
}

这样spring mvc 就已经整合完毕了

建立mybatis环境

在UserDao中使用注解查询

代码语言：javascript复制
package club.twzw.dao;

import club.twzw.bean.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository
public interface UserDao {

    @Select("select * from user")
    public List<User> findAll();

}

创建mybatis的核心配置文件mysqlConfig.xml

代码语言：javascript复制
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org.//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

<!-- mybatis 的 主配置文件-->
<configuration>

    <environments default="mysql">
        <!--配置mysql-->
        <environment id="mysql">
            <!--配置事务类型-->
            <transactionManager type="JDBC"/>
            <!--配置数据源/连接池-->
            <dataSource type="POOLED">
                <!--配置连接数据库的基本信息-->
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://xx.xx.xx:3306/learn?useSSL=false"/>
                <property name="username" value="learn"/>
                <property name="password" value="123456"/>
            </dataSource>
        </environment>
    </environments>

    <!--指定映射配置文件的位置，映射配置文件指的是每个dao独立的配置文件-->
    <mappers>
        <!--使用xml进行查询-->
        <!--<mapper resource="mapper/UserDao.xml"/>-->
        <!--使用注解-->
        <!--<mapper class="club.twzw.dao.UserDao"/>-->
        <!--扫描mapper下所有注解-->
        <package name="mapper"/>
    </mappers>

</configuration>

书写测试方法

代码语言：javascript复制
    @Test
    public void test() throws IOException {
        InputStream resourceAsStream = Resources.getResourceAsStream("mysqlConfig.xml");
        SqlSessionFactoryBuilder builder = new SqlSessionFactoryBuilder();
        SqlSessionFactory factory = builder.build(resourceAsStream);
        SqlSession session = factory.openSession(true);

        UserDao mapper = session.getMapper(UserDao.class);
        List<User> all = mapper.findAll();
        for (User user : all) {
            System.out.println(user);
        }
    }

输出结果：

说明了mybatis可用，那么可以开始整合了

整理mybatis,思路相同，同样使用依赖注入，将mysqlConfig.xml添加到容器中，并自动注入

在spring的文件中整合mybatis,配置连接池，factory，dao所在的包,此时有无将mysqlConfig.xml都不重要！

使用依赖注入

在dao类上添加@Repository注解

代码语言：javascript复制
@Repository					<<<<<--------
public interface UserDao {

    @Select("select * from user")
    public List<User> findAll();
}

在serviceimpl中注入接口

代码语言：javascript复制
package club.twzw.service.impl;

import club.twzw.bean.User;
import club.twzw.dao.UserDao;
import club.twzw.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service("UserService")
public class UserServiceImpl implements UserService {


    @Autowired
    private UserDao dao;

    public List<User> findAll() {
        System.out.println("查询所有用户。。。");
        return dao.findAll();
    }
}

修改controllerfindAll方法

代码语言：javascript复制
package club.twzw.controller;

import club.twzw.bean.User;
import club.twzw.service.impl.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
public class UserController {

    @Autowired
    private UserService service;


    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("success");
        List<User> all = service.findAll();
        model.addAttribute("user",all);
        return "list";
    }
}

添加list.jsp

controller

代码语言：javascript复制
    @RequestMapping("/save")
    public String save(Model model){
        System.out.println("success");
        User u = new User();
        u.setEmail("184611875@qq.com");
        u.setGender("男");
        u.setName("comi");
        boolean b = service.Save(u);
        System.out.println(b);
        return "success";
    }

UserService

代码语言：javascript复制
package club.twzw.service;

import club.twzw.bean.User;
import org.springframework.stereotype.Service;

import java.util.List;

public interface UserService {
    public List<User> findAll();

    public boolean Save(User u);
}

UserServiceImpl

代码语言：javascript复制
package club.twzw.service.impl;

import club.twzw.bean.User;
import club.twzw.dao.UserDao;
import club.twzw.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service("UserService")
public class UserServiceImpl implements UserService {


    @Autowired
    private UserDao dao;

    public List<User> findAll() {
        System.out.println("查询所有用户。。。");
        return dao.findAll();
    }

    @Override
    public boolean Save(User u) {
        return dao.Save(u);
    }
}

dao

代码语言：javascript复制
package club.twzw.dao;

import club.twzw.bean.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository
public interface UserDao {

    @Select("select * from user")
    public List<User> findAll();

    @Insert("insert into user (name,gender,email) values(#{name},#{gender},#{email})")
    public boolean Save(User u);
}

输出：

访问路径(http://localhost:8080/ssmWork_war_exploded/save) 这样我们的ssm框架就完成整合了，可以去干大事了！！！！ 码云开源库：码云链接
