Error creating bean with name ‘requestMappingHandlerAdapter’ OR java.lang.IllegalStateException: Failed to load ApplicationContext

Error creating bean with name ‘requestMappingHandlerAdapter’ defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans

背景： 最近在弄一个项目的重构，从SSM项目重构成SpringBoot项目，并且需要将其模块化，orm也从mybatis到mybatis-plus,但今天刚刚搭建初始环境和Dao层，一测就报这个错误。头大，给记录一下，也给大家提供一个解决方案哈。

根据错误我一直百度，总结了一下网上大家说的，大概有以下几点：

  • 有的说是 jackson jar包版本低了 把版本修改了就行了
  • 还有可能是jar 包冲突了 解决冲突也能行
  • 还有可能是 兼容问题哈

<!--json-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.33</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.0</version>
</dependency>

可以先都试一试哈，没有给大家找完全哈。

解决

最后我找到的解决方式 就是因为这句话 使Jackson支持JSR310标准

然后最后导入了下面这个依赖：

代码语言：javascript复制
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.9.2</version>
</dependency>

当然，并不是所有人都是这样的原因，如果没对，我也没有办法啦，那就得继续 百度百度哈。

自言自语

有些问题是真的难找啊。
