全局自定义异常处理 - service层直接抛出异常 （demo）

1.创建自定义返回参数类（ResultInfoVO）

2.定义自定义异常信息类( BuessExcetion extends RuntimeException)

3.定义全局异常处理类 （GlobalExceptionHandler）

代码：

ResultInfoVO

public class ResultInfoVO {

    private Integer code;

    private Boolean result;

    private String message;

    public ResultInfoVO(String message) {
        this.message = message;
    }

    public ResultInfoVO(Integer code, Boolean result, String message) {
        this.code = code;
        this.result = result;
        this.message = message;
    }

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public Boolean getResult() {
        return result;
    }

    public void setResult(Boolean result) {
        this.result = result;
    }

    public String getMessage() {
        return message;
    }

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

自定义异常信息类：

public class BuessExcetion extends RuntimeException {

public BuessExcetion(String message){
    super(message);
}
}

全局异常处理类：

@ControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(BuessExcetion.class)
    @ResponseBody
    public ResultInfoVO handleIllegalArgumentPlumException(BuessExcetion e) {
        String message = e.getMessage();
        return new ResultInfoVO(message);
    }

}

测试:

public class CtuServiceImp  {
    public String aa()   {
            if (1 == 1) {
                throw new BuessExcetion("aa");
            }
        return "";
    }
}

结果:
