## 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。
