\# SSM项目整合  
\#\# 先创建一个maven工程  
按maven规范创建包  
\* src  
\* main  
\* java  
\* resources  
\* webapp  
\* test  
1. 在pom.xml中导入相关的jar包

2. 如果想要在source目录中创建配置文件，则需要在pom.xml中添加如下代码  
\`\`\`  
<build>  
<finalName>Day57\_SSM整合</finalName>  
  
  
  
<resources>  
  
  
  
<resource>  
<directory>src/main/java</directory>  
<includes>  
  
  
  
<include>\*\*/\*.properties</include>  
<include>\*\*/\*.xml</include>  
</includes>  
  
<filtering>false</filtering>  
</resource>  
  
<resource>  
<directory>src/main/resources</directory>  
  
</resource>  
</resources>  
</build>  
\`\`\`  
3. 在resources目录下创建db.properties（c3p0配置文件）  
\`\`\`  
\# 配置四大参数  
db.driver=com.mysql.jdbc.Driver  
db.url=jdbc:mysql://localhost:3306/mybatis  
db.username=root  
db.password=123  
\# 池配置  
db.initialPoolSize=20  
db.maxIdleTime=60  
db.maxPoolSize=200  
db.minPoolSize=50  
db.acquireIncrement=3  
db.acquireRetryDelay=1000  
db.acquireRetryAttempts=30  
db.breakAfterAcquireFailure=false  
\`\`\`  
4. 在resources目录下创建spring配置文件，spring-config.xml  
\`\`\`  
<?xml version="1.0" encoding="UTF-8"?>

<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>  
</bean>  
  
  
</beans>  
\`\`\`  
5. 在resources目录下创建Mybatis配置文件SQLMapConfig.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>  
  
<properties resource="db.properties"/>  
<settings>  
  
<setting name="lazyLoadingEnabled" value="true"/>  
  
  
  
<setting name="aggressiveLazyLoading" value="false"/>  
  
  
  
<setting name="cacheEnabled" value="true"/>  
</settings>  
<typeAliases>  
  
  
</typeAliases>  
<environments default="development">  
<environment id="development">  
<transactionManager type="JDBC"/>  
<dataSource type="POOLED">  
<property name="driver" value="$\{db.driver\}"/>  
<property name="url" value="$\{db.url\}"/>  
<property name="username" value="$\{db.username\}"/>  
<property name="password" value="$\{db.password\}"/>  
</dataSource>  
</environment>  
</environments>  
<mappers>  
<package name="com.ssm.\*.dao"/>  
</mappers>  
</configuration>  
\`\`\`  
6. 配置web.xml  
\`\`\`  
<!DOCTYPE web-app PUBLIC  
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"  
"http://java.sun.com/dtd/web-app\_2\_3.dtd" >  
  
  
<web-app>  
<display-name>Archetype Created Web Application</display-name>  
  
<context-param>  
<param-name>contextConfigLocation</param-name>  
<param-value>classpath:spring-config.xml</param-value>  
</context-param>  
  
  
  
  
<context-param>  
<param-name>log4jRefreshInterval</param-name>  
<param-value>60000</param-value>  
</context-param>  
  
  
  
<filter>  
<filter-name>characterEncoding</filter-name>  
<filter-class>org.springframework.web.filter.CharacterEncodingFilter  
</filter-class>  
<init-param>

</servlet>  
<servlet-mapping>  
<servlet-name>springmvc</servlet-name>  
<url-pattern>/</url-pattern>  
</servlet-mapping>  
</web-app>  
\`\`\`  
\*\*到这就配置完毕了，是不是很简单\*\*  
\*\*\*  
\*\*我们写个类来测试一下\*\*  
1. 在java下创建包com.ssm.user  
2. 在user包下创建四个包  
\* controller  
\* dao  
\* domain  
\* service  
  
  
\*你可以和我不一样，但一定要符合配置文件中的规范\*  
\`\`\`  
  
<property name="basePackage" value="com.ssm.\*.dao"/>  
\`\`\`  
\`\`\`  
<aop:pointcut id="pointCut" expression="execution(\* com.ssm.\*.dao.\*.\*(..))"/>  
\`\`\`  
\`\`\`  
<mappers>  
<package name="com.ssm.\*.dao"/>  
</mappers>  
\`\`\`  
3. 在创建domain包下创建User类  
\*请自行创建mybatis数据库和user表\*  
\`\`\`  
package com.ssm.user.domain;  
  
  
public class User \{  
private int id;  
private String username;  
  
  
public User() \{  
\}  
  
  
public int getId() \{  
  
  
return id;  
\}  
  
  
public void setId(int id) \{  
this.id = id;  
\}  
  
  
public String getUsername() \{  
return username;  
\}  
  
  
public void setUsername(String username) \{  
this.username = username;  
\}  
\}  
\`\`\`  
4. 在dao包下创建UserMapper和UserMapper.xml  
\`\`\`  
package com.ssm.user.dao;  
  
  
import com.ssm.user.domain.User;  
import org.springframework.stereotype.Repository;  
  
  
@Repository  
public interface UserMapper \{  
User findUserById(int id);  
  
  
void insertUser(User user);  
\}  
  
  
\`\`\`  
\`\`\`  
<?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="com.ssm.user.dao.UserMapper">  
<insert id="insertUser"  
parameterType="com.ssm.user.domain.User">  
INSERT INTO USER (id,username)  
VALUES (\#\{id\},\#\{username\})  
</insert>  
<select id="findUserById" parameterType="int" resultType="com.ssm.user.domain.User">  
SELECT \* FROM user WHERE id = \#\{id\}  
</select>  
</mapper>  
\`\`\`  
5. 在controller包下创建UserController类  
\`\`\`  
<?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="com.ssm.user.dao.UserMapper">  
<insert id="insertUser"  
parameterType="com.ssm.user.domain.User">  
INSERT INTO USER (id,username)  
VALUES (\#\{id\},\#\{username\})  
</insert>  
<select id="findUserById" parameterType="int" resultType="com.ssm.user.domain.User">  
SELECT \* FROM user WHERE id = \#\{id\}  
</select>  
</mapper>  
\`\`\`  
6.在WEB\_INF/pages下创建login.jsp和register.jsp  
\`\`\`  
<%@ page contentType="text/html;charset=UTF-8" language="java" %>  
<html>  
<head>  
<title>login.jsp</title>  
</head>  
<body>  
<h1>SUCCESS</h1>  
</body>  
</html>  
\`\`\`  
\`\`\`  
<%@ page contentType="text/html;charset=UTF-8" language="java" %>  
<%@ page isELIgnored="false" %>  
<html>  
<head>  
<title>注册页面</title>  
</head>  
<body>  
<form action="$\{pageContext.request.contextPath\}/user/register"  
method="post">  
<input type="text" name="username">  
<input type="submit">  
</form>  
</body>  
</html>  
  
  
\`\`\`

9. 更改程序中的错误  
10. 更改程序中的错误  
11. 更改程序中的错误  
12. 更改程序中的错误
