Spring mvc中junit测试遇到com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException错误怎么解决

今天遇到图片中的错误，纠结了一下，弄清楚了怎么从控制台中读取错误信息，并修改错误。

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''d_id'=d.'dept_id') tmp_count' at line 7  显示我的错误是mysql语句错误，所以只需要修改代码中的mysql语句就可以了。

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.jdbc.BadSqlGrammarException:

### Error querying database.  Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''d_id'=d.'dept_id') tmp_count' at line 7

### The error may exist in file [F:\workspaces\xiaofan\target\classes\mapper\EmployeeMapper.xml]

### The error may involve defaultParameterMap

### The error occurred while setting parameters

### SQL: select count(0) from (select           worker_id, worker_name, worker_gender, worker_email, d_id      FROM worker e   LEFT JOIN dept d ON e.'d_id'=d.'dept_id') tmp_count

### Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''d_id'=d.'dept_id') tmp_count' at line 7
