需要引入jar包为

<dependency>
    <groupId>net.logstash.logback</groupId>
    <artifactId>logstash-logback-encoder</artifactId>
    <version>4.9</version>
</dependency>

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.3.1.Final</version>
</dependency>

异常类创建

/**
 * <p>Description: 异常封装类</p>
 * @author xu_jinhang
 * @versions 1.5.0
 * @date 2020/4/24 11:21
 */
public class BizException extends RuntimeException {
    /**
     *
     */
    private static final long serialVersionUID = 1L;

    public BizException() {
    }

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

    public BizException(ReturnCodeEnum returnCode) {
        super(returnCode.getCodeString() + "$$" + returnCode.getMsg());
    }

    public BizException(String message, Throwable cause) {
        super(message, cause);
    }

    public BizException(Throwable cause) {
        super(cause);
    }

    public BizException(String message, Throwable cause,
                        boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

异常拦截处理工具
