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。
