编写crm项目时浏览器上，出现" Handler dispatch failed; nested exception is java.lang.StackOverflowError"错误

type Exception report

message Handler dispatch failed; nested exception is java.lang.StackOverflowError

description The server encountered an internal error that prevented it from fulfilling this request.

出现StackOverflowError问题可以检查一下service层是否正确调用mapper。

错误原因代码：

package com.xie.crm.settings.service.impl;

import com.xie.crm.settings.mapper.DicValueMapper;
import com.xie.crm.settings.model.DicValue;
import com.xie.crm.settings.service.DicValueService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service("dicValueService")
public class DicValueServiceImpl implements DicValueService {
    @Autowired
    private DicValueService dicValueService;
    @Override
    public List<DicValue> queryDicValueByTypeCode(String typeCode) {
        return dicValueService.queryDicValueByTypeCode(typeCode);
    }
}

检查发现在service层调用service，出现错误，因此改为调用mapper层即可。

更改后：

package com.xie.crm.settings.service.impl;

import com.xie.crm.settings.mapper.DicValueMapper;
import com.xie.crm.settings.model.DicValue;
import com.xie.crm.settings.service.DicValueService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service("dicValueService")
public class DicValueServiceImpl implements DicValueService {
    @Autowired
    private DicValueMapper dicValueMapper;
    @Override
    public List<DicValue> queryDicValueByTypeCode(String typeCode) {
        return dicValueMapper.selectDicValueByTypeCode(typeCode);
    }
}

更改项目代码后，重新运行代码，即可正常运行。文章来源地址https://www.toymoban.com/news/detail-699253.html
