springboot整合jwt与vue的后端管理系统2

接着上篇我们先把security的依赖注释不然每次都要账号密码

然后代码后测试一下自动代码的成功

首先在controller建立一个TestController:

@RestController
public class TestController {
    @Autowired
    SysUserService userService;
    @GetMapping("/test")
    public Object test(){
         return  userService.list();
    }
}

测试结果

后接下来对数据统一封装建立一个封装类建一个包common在这个包在一个lang包然后建一个Result类进行数据封装

@Data
public class Result implements Serializable {
    private int code;
    private String msg;
    private Object data;
    public static Result succ(Object data) {
        return succ(200, "操作成功", data);
    }
    public static Result succ(int code, String msg, Object data) {
        Result r = new Result();
        r.setCode(code);
        r.setMsg(msg);
        r.setData(data);
        return r;
    }
    public static Result fail(String msg) {
        return fail(400, msg, null);
    }
    public static Result fail(String msg, Object data) {
        return fail(400, msg, data);
    }
    public static Result fail(int code, String msg, Object data) {
        Result r = new Result();
        r.setCode(code);
        r.setMsg(msg);
        r.setData(data);
        return r;
    }
}

建立一个全局异常类处理该项目的异常处理

package com.rao.com.exception;

import com.rao.com.lang.Result;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.HttpStatus;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.validation.BindingResult;
import org.springframework.validation.ObjectError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;

@Slf4j
@RestControllerAdvice
public class GlobalExceptionHandler {
    @ResponseStatus(HttpStatus.FORBIDDEN)
    @ExceptionHandler(value = AccessDeniedException.class)
    public Result handler(AccessDeniedException e) {
        log.info("security权限不足：----------------{}", e.getMessage());
        return Result.fail("权限不足");
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public Result handler(MethodArgumentNotValidException e) {
        log.info("实体校验异常：----------------{}", e.getMessage());
        BindingResult bindingResult = e.getBindingResult();
        ObjectError objectError = bindingResult.getAllErrors().stream().findFirst().get();
        return Result.fail(objectError.getDefaultMessage());
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(value = IllegalArgumentException.class)
    public Result handler(IllegalArgumentException e) {
        log.error("Assert异常：----------------{}", e.getMessage());
        return Result.fail(e.getMessage());
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(value = RuntimeException.class)
    public Result handler(RuntimeException e) {
        log.error("运行时异常：----------------{}", e);
        return Result.fail(e.getMessage());
    }
}

处理办法如下：通过使用@ControllerAdvice来进行统一异常处理，@ExceptionHandler(value = RuntimeException.class)来指定捕获的Exception各个类型异常 ，这个异常的处理，是全局的，所有类似的异常，都会跑到这个地方处理。

步骤二、定义全局异常处理，@ControllerAdvice表示定义全局控制器异常处理，@ExceptionHandler表示针对性异常处理，可对每种异常针对性处理。

package com.rao.com.exception;

import com.rao.com.lang.Result;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.HttpStatus;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.validation.BindingResult;
import org.springframework.validation.ObjectError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;

@Slf4j
@RestControllerAdvice
public class GlobalExceptionHandler {
    @ResponseStatus(HttpStatus.FORBIDDEN)
    @ExceptionHandler(value = AccessDeniedException.class)
    public Result handler(AccessDeniedException e) {
        log.info("security权限不足：----------------{}", e.getMessage());
        return Result.fail("权限不足");
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public Result handler(MethodArgumentNotValidException e) {
        log.info("实体校验异常：----------------{}", e.getMessage());
        BindingResult bindingResult = e.getBindingResult();
        ObjectError objectError = bindingResult.getAllErrors().stream().findFirst().get();
        return Result.fail(objectError.getDefaultMessage());
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(value = IllegalArgumentException.class)
    public Result handler(IllegalArgumentException e) {
        log.error("Assert异常：----------------{}", e.getMessage());
        return Result.fail(e.getMessage());
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(value = RuntimeException.class)
    public Result handler(RuntimeException e) {
        log.error("运行时异常：----------------{}", e);
        return Result.fail(e.getMessage());
    }
}
