IDEA中使用Maven搭建SSM框架：https://www.cnblogs.com/xuyiqing/p/10522339.html
Eclipse新建Maven Project->archetype选择webapp
Window-Preferences->搜索JRES配置本地JDK（推荐1.8，过高或过低可能出现未知问题）
Window-Preferences->搜索Maven配置本地Maven和settings.xml
Window-Preferences->搜索Server配置本都Tomcat
然而新建好的Maven Project是报错的
解决：选中项目右键Properties->Java Build Path->Libraries->Add Library，添加Server Runtime，应用后就不会报错了
pom.xml加入Maven编译插件，并配置JDK和编码：
<build>
<finalName>xxx</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF8</encoding>
</configuration>
</plugin>
</plugins>
</build>
保存后，项目右键Maven->Update ...
由于自动构建的项目缺少src/test/resources目录，可以选择性地自行创建
Java Resource目录右键new source folder：
Project Name和项目名一致
Folder Name：src/test/resources
完成后
项目右键Properties->Java Build Path->Source
如果是最新版Eclipse，在src/test/java中选中Contains Test Source->Toggle
src/test/resources设置Output和src/test/java地Output路径一致
应用
设置Project Facets：可以省略，我设置只是为了提高效率
项目右键设置properties->搜索facets，设置Dynamic Web Module为3.1
发现设置失败，这是Eclipse的BUG，无论新旧版本
解决办法：进入项目路径.settins目录，打开目录中的XML文件：修改为下图所示
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="wst.jsdt.web"/>
<installed facet="jst.web" version="3.1"/>
<installed facet="wst.jsdt.web" version="1.0"/>
<installed facet="java" version="1.8"/>
</faceted-project>
web.xml也要修改为3.1版本：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1" metadata-complete="true"> <display-name>Archetype Created Web Application</display-name>
</web-app>
测试：启动项目，如果正常跳到index.jsp说明准备工作顺利完成
接下来开始正式搭建SSM框架：
pom.xml：我选取了SSM框架和一些常用的包作为依赖
<?xml version="1.0" encoding="UTF-8"?>

新建两个source folder:
src/main/resources/spring：用于放Spring配置文件
src/main/resources/mapper：用于放MyBatis的映射文件
在src/main/resources下创建数据库连接配置文件：jdbc.properties：
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=xxx
在src/main/resources下创建MyBatis配置文件：mybatis-config.xml：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">

</configuration>
配置Spring：
在src/main/resources/spring下创建spring-dao.xml：

web.xml中对Spring进行配置：顺便我也配置了验证码插件Kaptcha
<?xml version="1.0" encoding="UTF-8"?>

到这里就配置完成了！
下面进行测试：
我写一个简单的实体类，并在数据库加入一条信息
package org.dreamtech.xiuxian.entity;
public class Person {
private String userId;
private Integer exp;
private String stateId;
private String username;
private String password;
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public Integer getExp() {
return exp;
}
public void setExp(Integer exp) {
this.exp = exp;
}
public String getStateId() {
return stateId;
}
public void setStateId(String stateId) {
this.stateId = stateId;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "Person [userId=" + userId + ", exp=" + exp + ", stateId=" + stateId + ", username=" + username
+ ", password=" + password + "]";
}
}
Dao层测试：
package org.dreamtech.xiuxian.dao; import org.apache.ibatis.annotations.Param;
import org.dreamtech.xiuxian.entity.Person; public interface PersonDao {
/**
* 根据用户名和密码得到用户信息
*
* @return 用户
*/
Person getPersonByUsernameAndPassword(@Param("username") String username, @Param("password") String password);
}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="org.dreamtech.xiuxian.dao.PersonDao">
<select id="getPersonByUsernameAndPassword" resultType="Person">
SELECT
user_id,exp,state_id,username,password
FROM
tb_person
WHERE
username=#{username}
AND
password=#{password}
</select>
</mapper>
package org.dreamtech.xiuxian.dao; import org.dreamtech.xiuxian.entity.Person;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:spring/spring-dao.xml" })
public class DaoTest {
@Autowired
private PersonDao personDao; @Test
public void testPersonDao() {
Person person = personDao.getPersonByUsernameAndPassword("test", "test");
System.out.println(person.getUserId());
}
}
Dao层测试成功！
Service层测试：
package org.dreamtech.xiuxian.service;
import org.dreamtech.xiuxian.entity.Person;
public interface PersonService {
/**
* 根据用户名和密码得到用户信息
*
* @return 用户
*/
Person getPersonByUsernameAndPassword(String username, String password);
}
package org.dreamtech.xiuxian.service.impl; import org.dreamtech.xiuxian.dao.PersonDao;
import org.dreamtech.xiuxian.entity.Person;
import org.dreamtech.xiuxian.service.PersonService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service; @Service
public class PersonServiceImpl implements PersonService {
@Autowired
private PersonDao personDao; @Override
public Person getPersonByUsernameAndPassword(String username, String password) {
if (username != null && !username.equals("")) {
username = username.replace(" ", "");
} else {
throw new RuntimeException("username is null");
}
if (password != null && !password.equals("")) {
password = password.replace(" ", "");
} else {
throw new RuntimeException("password is null");
}
Person person = null;
try {
person = personDao.getPersonByUsernameAndPassword(username, password);
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException("error:PersonDao.getPersonByUsernameAndPassword");
}
return person;
} }
package org.dreamtech.xiuxian.service; import org.dreamtech.xiuxian.entity.Person;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:spring/spring-dao.xml", "classpath:spring/spring-service.xml" })
public class ServiceTest {
@Autowired
private PersonService personService; @Test
public void testPersonDao() {
Person person = personService.getPersonByUsernameAndPassword("test", "test");
System.out.println(person.getUserId());
}
}
Service层测试成功！
Controller层测试：
package org.dreamtech.xiuxian.web; import java.util.HashMap;
import java.util.Map; import javax.servlet.http.HttpServletRequest; import org.dreamtech.xiuxian.entity.Person;
import org.dreamtech.xiuxian.service.PersonService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController; @RestController
@RequestMapping("/person")
public class PersonController {
@Autowired
private PersonService personService; @RequestMapping("login")
private Map<String, Object> login(HttpServletRequest request) {
String username = request.getParameter("username");
String password = request.getParameter("password");
Map<String, Object> modelMap = new HashMap<String, Object>();
try {
Person person = personService.getPersonByUsernameAndPassword(username, password);
modelMap.put("person", person);
modelMap.put("success", true);
} catch (Exception e) {
modelMap.put("success", false);
}
return modelMap;
}
}
Controller层就不需要写测试类了，直接访问：
http://localhost:8080/xiuxian/person/login?username=test&password=test
所有测试完成！
