springboot异常处理

方式1：配置方式实现

---

springboot异常全局配置：applocation.yml

server:
  port: 8771
  error:
    include-message: always
    include-exception: false
    include-stacktrace: never

实验代码：

@GetMapping("/doUser")
@ResponseBody
public String doUser(@RequestHeader(value = "flag") String flag) {
    if (flag.equals("1")) {
        throw new RuntimeException("发生运行异常");
    }
    return flag;
}

运行结果：

方式2：切面代码实现

---

@RestControllerAdvice
public class CustomExtHandler {

    //捕获全局异常,处理所有不可知的异常
    @ExceptionHandler(value=Exception.class)
    public Object handleException(Exception e, HttpServletRequest req){
        Map<String, Object> map = new HashMap<>();
        Calendar calendar = Calendar.getInstance();
        map.put("timestamp", calendar.getTime());
        map.put("status", 500);
        map.put("error", "Internal Server Error");
        map.put("message", e.getMessage());
        map.put("path", req.getRequestURI());
        return map;
    }
}

结果：

自定义异常处理

---

public class SunpyException extends RuntimeException {

    private String path;

    private String error;

    private String message;

    private Date timestamp;

    private int status;

    public String getPath() {
        return path;
    }

    public void setPath(String path) {
        this.path = path;
    }

    public String getError() {
        return error;
    }

    public void setError(String error) {
        this.error = error;
    }

    @Override
    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public Date getTimestamp() {
        return timestamp;
    }

    public void setTimestamp(Date timestamp) {
        this.timestamp = timestamp;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }
}

实验代码：

@GetMapping("/doUser")
@ResponseBody
public String doUser(@RequestHeader(value = "flag") String flag, HttpServletRequest req) throws SunpyException{
    if (flag.equals("1")) {
        SunpyException e = new SunpyException();
        e.setError("Internal Server Error");
        e.setPath(req.getRequestURI());
        e.setMessage("发生运行异常");
        e.setStatus(500);
        Calendar calendar = Calendar.getInstance();
        e.setTimestamp(calendar.getTime());
        throw e;
    }
    return flag;
}

捕获显示异常：
可以采取上面的方式1或者方式2

结果：
