java开发实战(2):springboot工程引入日志配置和swagger3

根据上一步的操作创建了三个子模块,分别是:

  • demo-admin: 程序入口
  • demo-user:用户管理模块
  • demo-common: 公共模块,所有模块都依赖

配置日志logback:

logback是springboot的内置日志框架,所以比较方便;

直接在resources文件夹下新建logback.xml文件既可

logback.xml是放到了demo-admin模块中,因为此模块是程序入口,方便日志的统一;

在demo-admin模块的pom文件中添加依赖:

主要依赖了springboot的web和其他模块

            <artifactId>demo-user</artifactId>

logback.xml文件配置:

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="false" scanPeriod="60 seconds" debug="false">

    <property name="LOG_PATH" value="logs" />

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
            </Pattern>
        </layout>
    </appender>

    <appender name="FILE-AUDIT"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_PATH}/debug.log</file>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
            </Pattern>
        </encoder>

        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- rollover daily -->
            <fileNamePattern>${LOG_PATH}/debug.%d{yyyy-MM-dd}.%i.log
            </fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy
                    class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>

    </appender>

    <appender name="FILE-ERROR"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_PATH}/error.log</file>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">

            </Pattern>
        </encoder>

        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- rollover daily -->
            <fileNamePattern>${LOG_PATH}/error.%d{yyyy-MM-dd}.%i.log
            </fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy
                    class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>

    </appender>

    <!-- Send logs to both console and file audit -->
    <logger name="com.exp" level="debug" additivity="false">
        <appender-ref ref="FILE-AUDIT" />
        <appender-ref ref="STDOUT" />
    </logger>

    <root level="error">
         <appender-ref ref="FILE-ERROR" />
    </root>
    <root level="INFO">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE-AUDIT" />
       <!-- <appender-ref ref="FILE-ERROR" />-->
    </root>

</configuration>

编码启动类:

代码语言:java复制
import org.springframework.boot.SpringApplication;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.ImportAutoConfiguration;
import org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration;


@SpringBootConfiguration
@EnableAutoConfiguration
@ImportAutoConfiguration(classes = {
},exclude = {
       // MongoDataAutoConfiguration.class,
        MongoAutoConfiguration.class
})
public class AdminApplication {

    public static void main(String[] args) {
        SpringApplication.run(AdminApplication.class,args);
    }
}

在idea中启动程序,可以再模块的同级目录中生成logs文件夹

引入swagger3:

swagger是一个接口管理工具,springboot集成swagger可以生成接口管理页面,方便调试;

  • 第一步:创建接口;
代码语言:java复制
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping(value = "/server")
public class ServerController {

    @GetMapping(value = "/test")
    public WebResult<String> test(){
        return  WebResult.build("it is work!");
    }
}

此处创建了一个GET接口,测试接口服务是否正常;

WebResult是一个返回值包装类,用于同一返回值;

  • 第二步:引入swagger3的依赖:

关于swagger3:

目前大部分使用的是swagger2.但是2已经停止维护了。swagger3是swagger2的升级版,更易于与springboot集成;

此次依赖的引入放到了demo-common模块中,方便后续其他模块依赖common接可以直接使用swagger;

在demo-common的pom文件中添加依赖:

代码语言:html复制
 <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-ui</artifactId>
            <version>1.4.3</version>
        </dependency>

在java配置代码中添加OpenApi:

代码语言:java复制
 @Bean
    public OpenAPI openAPI() {
        return new OpenAPI()
                .info(new io.swagger.v3.oas.models.info.Info()
                        .title("demo API")
                        .description("接口后台")
                        .termsOfService("http://www.demo.com")
                        .contact(new io.swagger.v3.oas.models.info.Contact()
                                .name("xxxx有限公司")
                                .url("http://www.demo.com")
                                .email("service@demo.com")
                        )
                        .license(new io.swagger.v3.oas.models.info.License()
                                .name("XXX all rights reserved")
                                .url("http://www.demo.com")
                        )
                        .version(getVersion(getClass()))
                );
    }

在demo-admin中运行启动类;

访问

http://127.0.0.1:port/swagger-ui

swagger3基本不需要额外的配置;

如果不想启用swagger3,可添加配置

#swagger配置 默认true

springdoc.api-docs.enabled=false
