IDEA搭建SSMM框架（詳細過程）
相關環境
- Intellij IDEA Ultimate
- Tomcat
- JDK
- MySql 5.6（win32/win64）
- Maven （可使用Intellij IDEA自帶的）
搭建步驟
創建項目工程
1、創建工程，選擇Maven
2、填寫項目信息
初始化配置
1、Maven配置
先說Maven的項目依賴配置文件pom.xml，我們進入mvn repository 查找需要搜索的包結果如圖：
點擊進入第一個搜索結果，然后各種版本
點擊所需版本。如圖：
里面的dependency即為所需標簽。
工程整體結構
總體工程結構：
包括：Maven包依賴配置文件pom.xml、springMVC配置文件spring-mvc.xml、mybatis數據看配置文件spring-mybatis.xml jdbc.properties以及mybatis自動構建數據庫工具配置文件generatorConfig.xml generator.properties、log日志配置文件log4j.properites、web配置文件web.xml、java類相關等。
IDEA默認快捷鍵選中+F4喚出工程設置，可以配置相關的Sources、Tests、Resources等文件夾類型。
Maven配置文件
pom.xml添加依賴包信息如下：

點擊構建插件
輸入命令：mybatis-generator:generate -e
選中generator插件，點擊運行即可，在generatorConfig.xml配置的相關文件將會自動生成。其中數據庫驅動包需要指定路徑。構建的內容如下所示。
注意：
在IDEA中，生成在mapping中的xml會報找不到的錯誤，這將mapping中的內容拷貝到resources/mapper中，並指定mapper為resources類型文件夾。
對應spring—mybatis.xml中的如下內容：
<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自動掃描mapping.xml文件 --> <!--<property name="mapperLocations" value="classpath:com/ssm/mapping/*.xml"></property>--><!--在IDEA中配置會報錯，改成放在resources/mapper下--> <property name="mapperLocations" value="classpath:/mapper/*.xml"></property> </bean>
Java類
在main文件夾下創建文件夾java，點擊右鍵將java作為source文件夾，並生成相應包結構：
service
接口
// UserService.java
package com.ssm.service;
import com.ssm.model.User;
public interface UserService {
public User findUserById(int id);
public void addUser(User user);
}
實現類
// UserServiceImpl.java
package com.ssm.service;
import com.ssm.dao.UserMapper;
import com.ssm.model.User;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.Resource;
@Transactional
@Service
public class UserServiceImpl implements UserService {
@Resource
private UserMapper userMapper;
public User findUserById(int id) {
return userMapper.selectByPrimaryKey(id);
}
public void addUser(User user) {
userMapper.insert(user);
}
}
測試類
將java文件夾設置為Tests類型,並添加測試類
// TestMybatis.java
package com.ssm.test;
import com.alibaba.fastjson.JSON;
import com.ssm.model.User;
import com.ssm.service.UserService;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.annotation.Resource;
@RunWith(SpringJUnit4ClassRunner.class) //表示繼承了SpringJUnit4ClassRunner類
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})
public class TestMybatis {
private Logger logger = Logger.getLogger(TestMybatis.class);
@Resource
private UserService userService;
@Test
public void findUserByIdTest() {
User user = userService.findUserById(1);
System.out.println(user.getUsername());
logger.info("值："+user.getUsername());
logger.info(JSON.toJSONString(user));
}
}
Controller
// UserController.java
package com.ssm.controller;
import com.ssm.model.User;
import com.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/QueryUser.action")
public String toIndex(HttpServletRequest request, Model model){
int userId = Integer.parseInt(request.getParameter("id"));
User user = this.userService.findUserById(userId);
model.addAttribute("user", user);
return "User";
}
}
JSP
// User.jsp
