父工程创建完成。　　

二、创建模块web，并配置

在工程内创建模块，右键项目-new-module：

只有一个输入名字的，其他都下一步

此时父工程的pom会多一点内容：

不管目前子模块什么内容，直接通过创建文件夹、文件的方式调整为下图所示：

修改pom文件如下：

至此web部分完成。也可以直接编写一个测试类，打包部署看看。

#6.0以上用com.mysql.cj.jdbc.Driver，有的应用不支持6.0以上版本，不得不降级。
db.dirverClass=com.mysql.jdbc.Driver

配置mybatis-config.xml

至此配置完成，可以编写样例测试。

四、编写案例、打包部署

在mybatis模块中创建如下目录，路径等信息参看配置文件的内容，并自行编写样例：
Alt text

web模块中编写测试类，包路径参看配置文件：

Alt text

HelloController：

package club.kittybunny.ssm.web.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

/**
 * @Author: bunny
 * @Description: 我是兔子我会喵，我叫喵星兔
 */
@RestController
@RequestMapping("/web")
public class HelloController {
    @Autowired
    private EmpService empService;

    @RequestMapping(value = "/allemps", method = {RequestMethod.GET})
    public List<Emp> get() {

        return empService.findAll();
    }
}

飘红问题直接根据提示引入依赖即可：
Alt text

直接Alt + Shift + Enter
Alt text

至此，案例已经完成。然后打包部署。

父工程目录下执行

mvn package

Alt text

结果如下：
Alt text

然后可以在
Alt text

web模块下找到ssm-web.war文件，部署到tongcat即可。
