cef异常处理_SpringBoot异常处理

1. 配置全局异常和自定义异常

异常处理类(包括全局和自定义)

@RestControllerAdvice

public class CustomExtHandler {

/**

* 处理全局异常

* 返回json数据，由前端去判断加载什么页面(推荐)

*/

@ExceptionHandler(value = Exception.class)

Object handleException(Exception e, HttpServletRequest request) {

log.error("url [{}], msg [{}]", request.getRequestURL(), e.getMessage());

Map map = new HashMap<>(3);

map.put("code", 500);

map.put("msg", e.getMessage());

map.put("url", request.getRequestURL());

return map;

}

/**

* 处理自定义异常

* 返回json数据，由前端去判断加载什么页面(推荐)

*/

@ExceptionHandler(value = MyException.class)

Object handleMyException(MyException e, HttpServletRequest request) {

log.error("url [{}], msg [{}]", request.getRequestURL(), e.getMessage());

Map map = new HashMap<>(3);

map.put("code", e.getCode());

map.put("msg", e.getMsg());

map.put("url", request.getRequestURL());

return map;

}

}

自定义异常类

@Getter

@Setter

public class MyException extends RuntimeException {

//状态码

private String code;

//错误信息

private String msg;

public MyException(String code, String msg) {

this.code = code;

this.msg = msg;

}

}

2.返回自定义页面

创建自定义页面位置，位置如下图：

Error Page

error.html位置

引入thymeleaf依赖

org.springframework.boot

spring-boot-starter-thymeleaf

异常处理类

@RestControllerAdvice

public class CustomExtHandler {

/**

* 处理自定义异常

* 进行页面跳转

*/

@ExceptionHandler(value = MyException.class)

Object handleMyException(MyException e, HttpServletRequest request) {

ModelAndView modelAndView = new ModelAndView();

modelAndView.setViewName("error.html");

modelAndView.addObject("msg", e.getMessage());

return modelAndView;

}

}

1. 配置全局异常和自定义异常 异常处理类(包括全局和自定义) @RestControllerAdvice public class CustomExtHandler { /** * 处理全局异常 * 返回json数据，由前端去判断加载什么页面(推荐) */ @ExceptionHandler(value = Exception.class) Object handleException(Exception e, HttpServletRequest request) { log.error("url [{}], msg [{}]", request.getRequestURL(), e.getMessage()); Map map = new HashMap<>(3); map.put("code", 500); map.put("msg", e.getMessage()); map.put("url", request.getRequestURL()); return map; } /** * 处理自定义异常 * 返回json数据，由前端去判断加载什么页面(推荐) */ @ExceptionHandler(value = MyException.class) Object handleMyException(MyException e, HttpServletRequest request) { log.error("url [{}], msg [{}]", request.getRequestURL(), e.getMessage()); Map map = new HashMap<>(3); map.put("code", e.getCode()); map.put("msg", e.getMsg()); map.put("url", request.getRequestURL()); return map; } } 自定义异常类 @Getter @Setter public class MyException extends RuntimeException { //状态码 private String code; //错误信息 private String msg; public MyException(String code, String msg) { this.code = code; this.msg = msg; } } 2.返回自定义页面 创建自定义页面位置，位置如下图：Error Page error.html位置 引入thymeleaf依赖 org.springframework.boot spring-boot-starter-thymeleaf 异常处理类 @RestControllerAdvice public class CustomExtHandler { /** * 处理自定义异常 * 进行页面跳转 */ @ExceptionHandler(value = MyException.class) Object handleMyException(MyException e, HttpServletRequest request) { ModelAndView modelAndView = new ModelAndView(); modelAndView.setViewName("error.html"); modelAndView.addObject("msg", e.getMessage()); return modelAndView; } }
