SpringBoot使用ExceptionHandler做异常处理

public class ProcessException extends RuntimeException {
 
    private static final long serialVersionUID = 1L;
 
    // 任务明细ID
    protected String rwmxid;
 
    public ProcessException(String rwmxid) {
        this.rwmxid = rwmxid;
    }
 
    public String getRwmxid() {
        return rwmxid;
    }
 
    public void setRwmxid(String rwmxid) {
        this.rwmxid = rwmxid;
    }
    
}
