使用的是 Alibaba 的，所以需要确定版本：
直接创建 SpringBoot 项目，然后改成父项目，做模块化开发：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.6.11</version>
<relativePath/>
</parent>
<packaging>pom</packaging>
<name>项目名</name>

exceptionhandler
创建包 exceptionhandler
import org.springframework.http.converter.HttpMessageNotReadableException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
/**
* 全局异常捕获
*
* @author ifeisier
* @since 1.0.0
*/
@ControllerAdvice
public class CommonExceptionHandler {
/**
* 前端传递的参数类型不对, 导致 JSON 反序列化错误
*/
@ExceptionHandler(HttpMessageNotReadableException.class)
@ResponseBody
public ? exceptionHandler(HttpMessageNotReadableException e) {
return ?;
}
}
