ssm框架搭建的基本配置（一站式教会你搭建）

首先是需要的jar包：

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.1.3.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.2.8</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.2</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.32</version>
</dependency>
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.mchange.c3p0</groupId>
<artifactId>com.springsource.com.mchange.v2.c3p0</artifactId>
<version>0.9.1.2</version>
</dependency>

然后是web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name></display-name>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</context-param>

<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>mvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

然后是springMVC配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

<!-- 指定controller的包名 -->
<context:component-scan base-package="controller"/>
<mvc:annotation-driven/>
<!--
视图解析器
/jsp/emp/list.jsp -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>

spring配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<context:component-scan base-package="service"></context:component-scan>
<tx:annotation-driven />

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="user" value="root"></property>
<property name="password" value="FuErMing@0317"></property>
<property name="jdbcUrl" value="jdbc:mysql:///kaoshi?useUnicode=true&amp;characterEncoding=utf8"></property>
</bean>

<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="typeAliasesPackage" value="pojo"></property>
<property name="mapperLocations">
<list>
<value>classpath:mapper/*.xml</value>
</list>
</property>
</bean>

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactory" ref="sessionFactory"></property>
<!-- mybatis扫描该包的接口，并且实现该接口 -->
<property name="basePackage" value="mapper"></property>
</bean>
</beans>

可能会用到的分页工具：

package com.baidu.util;

public class PageUtil {
private int currentPage;//当前页
private int prevPage; //上一页
private int nextPage; //下一页
private int endPage; //末页
private int count; //总条数
private int size; //一页条数
private int startPage; //开始的条数序列
private int totalPage; //总页数

public PageUtil(String page,Integer listCount,Integer pageSize){
initCurrentPage(page);
initPrevPage();
this.count = listCount;
this.size = pageSize;

initEndPage();
initNextPage();
initStartPage();
initTotalPage();
}

private void initTotalPage() {
totalPage = (count/size)+(count%size==0?0:1);
}

private void initStartPage() {
startPage = (currentPage - 1)*size;
}
private void initEndPage() {
if(count%size==0){
endPage = count/size;
}else{
endPage = count/size + 1;
}
}

private void initNextPage() {
if(currentPage == endPage){
nextPage = currentPage;
}else{
nextPage = currentPage + 1 ;
}
}
private void initPrevPage() {
if(currentPage==1){
prevPage = currentPage;
}else{
prevPage = currentPage - 1 ;
}

}

private void initCurrentPage(String page) {
page=page==null?"1":page;
currentPage = Integer.parseInt(page);
}

public int getCurrentPage() {
return currentPage;
}
public int getPrevPage() {
return prevPage;
}
public int getNextPage() {
return nextPage;
}
public int getEndPage() {
return endPage;
}
public int getCount() {
return count;
}
public int getSize() {
return size;
}
public int getStartPage() {
return startPage;
}
public int getTotalPage() {
return totalPage;
}
}

mapper.xml:

<?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="mapper.AMapper" >
<select id="getList" resultType="User">
select * from user
</select>

</mapper>
