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 reportmessage Handler dispatch failed; nested exception is java.lang.StackOverflowErrordescription 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 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 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。
