怎么在IDEA中格式化SQL代码

怎么在idea中格式化sql代码？很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。

1.1、建立连接，数据库服务器地址，账号，密码等…

1.2、基本操作，很多，增删改查，控制台SQl编写等等

SQL执行控制台，这里是格式化之后的，我们平时手写的SQL都是没有格式化的，注意这里提供了输入框，操作占位符的参数也很方便…

那么这里的格式化的SQL是怎么实现的呢？？

这里的哈，IDEA的快捷键 Ctrl + Alt + L，就可以格式化SQL

补充：解决idea的src目录下不能编译SQL语句的xml配置文件的问题

一：正常配置下的情况

编译的目录下不会编译映射配置文件.xml，但是resources目录中的文件都被编译出来。

pom.xml文件的配置

控制台无报错且网页报错404 找不到，或者500如下错误。

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userHandler': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'userDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'IUserDao' defined in file [D:\Tomcat\apache-tomcat-9.0.27\webapps\hrm01_war\WEB-INF\classes\com\hrm\user\dao\IUserDao.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. Cause: org.apache.ibatis.builder.BuilderException: Wrong namespace. Expected 'com.hrm.user.dao.IUserDao' but found 'com.hrm.user.dao.UserDao'.

二、解决方案

在pom文件中的build标签下配置该属性即可解决这个问题，但是要注意src前面不要加 / 。

一定不要写为：（/src/main/java）。

这样在编译目录下xml文件也被编译。

加入该配置后编译目录下有了映射配置文件，见上图IUserDao.xml。

控制台可以正常显示数据。
