配置pom文件

啟動類
package com.zz; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class,args); } }
自定義異常類
package com.zz.exception; public class UserNotExistException extends RuntimeException{ private static final long serialVersionUID = -1574716826948451793L; private String id; public UserNotExistException(String id){ super("user not exist"); this.id = id; } public String getId() { return id; } public void setId(String id) { this.id = id; } }
統一處理類
1. 在class上面加 @ControllerAdvice 表示全局異常處理類
2. 在方法的上面加@ExceptionHandler(UserNotExistException.class), 表示catch 到這個異常類型,并且在方法中處理, 不同的異常,可以通過不同的方法處理,每個方法上面都是通過這個注解括號里面的異常類來設置需要處理的異常類型。
package com.zz.handler; import com.zz.exception.UserNotExistException; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ControllerAdvice; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.bind.annotation.ResponseStatus; import java.util.HashMap; import java.util.Map; @ControllerAdvice public class ControllerExceptionHandler { //返回json的錯誤信息 @ExceptionHandler(UserNotExistException.class) @ResponseBody @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR) public Map<String, Object> handleUserNotExistsException(UserNotExistException e) { Map<String, Object> map = new HashMap<>(); map.put("id", e.getId()); map.put("message", e.getMessage()); return map; } //錯誤以后,跳轉到自己定義的錯誤頁面 @ExceptionHandler(ArithmeticException.class) public String handle1(ArithmeticException e) { System.out.println("handle1 500*到了**************"); return "/500.html"; } }
controller類
package com.zz.controller; import com.zz.exception.UserNotExistException; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("user") public class UserController { @GetMapping("/{id:\\d+}") public void get(@PathVariable String id) { throw new UserNotExistException(id); } @GetMapping("error2") public void get2() { int a=1/0; } }
