四总结

一、使用技术简介

Spring：

Spring是一个开源框架，主要目的是用来替代更加重量级的企业级Java技术，是一个轻量级的控制反转（IOC）和面向切面（AOP）的容器框架。

Spring MVC：

Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。

Mybatis：

MyBatis 是一款优秀的持久层框架，它支持定制化 SQL、存储过程以及高级映射。MyBatis 避免了几乎所有的 JDBC代码和手动设置参数以及获取结果集。MyBatis 可以使用简单的 XML 或注解来配置和映射原生信息，将接口和 Java 的 POJOs(Plain Old Java Objects,普通的 Java对象)映射成数据库中的记录。

Jetty：

Jetty是一个开源、基于标准、全功能实现的JAVA服务器。它在Apache2.0协议下发布，因此可以自由的用于商业用途和发行。首创于1995年，Jetty受益于一个广大的用户社区，有一个稳定的核心开发者来持续专著的开发。但是Jetty无处不见!

二、项目整合

2-1 新建Maven工程

1.新建Maven工程，File—>New–>Project

2.选择如图所示选项，点击“Next”：

3.构建项目坐标（GroupId、Artfactid、Version），点击“Next”：

4. 可以看到项目信息，点击“Next”

6.新建项目目录不全，右击项目点击“Open Module Settings”，补全项目结构。

至此，一个基本的maven web工程就建好了。按照自己的编程习惯，完善项目包。

2-2 整合SSM

配置文件目录如图：

1.pom.xml ，导入所需jar包：

</project>

2.新建jdbc属性文件：

jdbc.properties

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false&zeroDateTimeBehavior=convertToNull
jdbc_username=root
jdbc_password=111111
#定义最大连接数
c3p0.pool.size.max=20
#定义连接池保持的最小连接数
c3p0.pool.size.min=5
#定义连接池初始化时创建的连接数
c3p0.pool.size.ini=3
#连接池在获得新连接失败时重试的次数
c3p0.pool.size.increment=2

3.新建log4j日志文件：

log4j.properties

#定义LOG输出级别
log4j.rootLogger=info, console, debug, app, error

###Console ###

#定义日志输出目的地为控制台
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.console.Target = System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern = %d %p[%C:%L]- %m%n

### debug ###
log4j.appender.debug = org.apache.log4j.DailyRollingFileAppender
log4j.appender.debug.File = log/debug.log
log4j.appender.debug.Append = true
log4j.appender.debug.Threshold = DEBUG
log4j.appender.debug.DatePattern='.'yyyy-MM-dd
log4j.appender.debug.layout = org.apache.log4j.PatternLayout
log4j.appender.debug.layout.ConversionPattern = %d %p[%c:%L] - %m%n

### app ###
log4j.appender.app = org.apache.log4j.DailyRollingFileAppender
log4j.appender.app.File = log/app.log
log4j.appender.app.Append = true
log4j.appender.app.Threshold = INFO
log4j.appender.app.DatePattern='.'yyyy-MM-dd
log4j.appender.app.layout = org.apache.log4j.PatternLayout
log4j.appender.app.layout.ConversionPattern = %d %p[%c:%L] - %m%n

### Error ###
log4j.appender.error = org.apache.log4j.DailyRollingFileAppender
log4j.appender.error.File = log/error.log
log4j.appender.error.Append = true
log4j.appender.error.Threshold = ERROR
log4j.appender.error.DatePattern='.'yyyy-MM-dd
log4j.appender.error.layout = org.apache.log4j.PatternLayout
log4j.appender.error.layout.ConversionPattern =%d %p[%c:%L] - %m%n

#ibatis logger config
log4j.logger.com.swc=debug
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=debug
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=debug
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=debug
log4j.logger.java.sql.Connection=debug
log4j.logger.java.sql.Statement=debug
log4j.logger.java.sql.PreparedStatement=debug

4.一个web项目，最先读取的就是web.xml，配置如下：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="AdminEAP" version="3.0">

<!--spring配置文件-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring*.xml</param-value>
</context-param>
<!-- 配置监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!--针对spring MVC进行配置    -->
<servlet>
<servlet-name>spring-mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring*.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-mvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--解决乱码问题 字符集过滤 -->
<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>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<session-config>
<session-timeout>120</session-timeout>
</session-config>
</web-app>

5.新建Spring和MyBitis整合所需的配置文件：

spring-mybatis.xml

<?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"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> 
<!--包扫描 -->
<context:component-scan base-package="com.swc"/>

<!-- 导入jdbc配置信息 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置c3p0数据源-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc_driverClassName}"/>
<property name="jdbcUrl" value="${jdbc_url}"/>
<property name="user" value="${jdbc_username}"/>

<property name="initialPoolSize" value="${c3p0.pool.size.ini}"/>
<property name="acquireIncrement" value="${c3p0.pool.size.increment}"/>
</bean>
<!-- sessionFactory spring 和 mybatis整合-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<!--自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath*:mapper/*.xml"/>
</bean>
<!-- 生成dao 代理对象-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.swc.**.dao"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</bean>

<!--事务配置 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 配置开启事务操作-->
<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED"/>
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="insert*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="modify*" propagation="REQUIRED"/>
<tx:method name="get*" propagation="REQUIRED" read-only="true"/>
</tx:attributes>
</tx:advice>
<!--一般只对service层添加事务 -->
<!--第一个*：返回值类型 -->
<!--第二个*：类名以service结尾的类 -->
<!--第三个*：方法 -->
<!--第一个..：方法可以有0个或多个参数 -->
<aop:config>
<aop:pointcut id="transactionPointcut" expression="execution(* com.swc..*service.*(..))"/>
<aop:advisor advice-ref="transactionAdvice" pointcut-ref="transactionPointcut"/>
</aop:config>
</beans>

6.新建整合SpringMVC所需的配置文件

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 
<!-- 默认注解映射的支持-->
<mvc:annotation-driven/>
<!-- 自动扫描该包，使springMVC认为该包下，使用注解@Controller的类是控制器-->
<context:component-scan base-package="com.swc.**.controller"/>
<!-- 避免IE执行AJAX，返回json出现下载文件-->
<bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes" >
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 定义跳转文件的前后端，视图模式配置 -->
<!-- 自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".html"/>
</bean>
<!--配置文件上传 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8"/>
<property name="maxUploadSize" value="10485760000"/>
<property name="maxInMemorySize" value="40960"/>
</bean>
</beans>

通过以上步骤，完成SSM的整合工作，接下来可以测试是否成功，完成项目配置和部署。

三、项目测试和部署

3-1 测试

构建完整项目目录：

1.数据库新建表tbl_user：

//创建表tbl_user
create table tbl_user (
id INT PRIMARY KEY AUTO_INCREMENT,,
name VARCHAR(225) NOT NULL,
sex VARCHAR(225) NOT NULL,
passwordVARCHAR(225) NOT NULL,
address VARCHAR(225)
)

//添加数据
INSERT INTO `mybatis`.`tbl_user` (`id`, `name`, `sex`, `address`) VALUES (1, '宋先生', '男', '111111','北京市朝阳区');
INSERT INTO `mybatis`.`tbl_user` (`id`, `name`, `sex`, `address`) VALUES (2, '李女士', '女','222222', '北京市海淀区');

实体类 User.java

package com.swc.base.entity;

/**
* Created by chao on 2018-2-1.
*/
public class User {

private Integer id;
private String name;
private String sex;
private String address;
private String password;

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getSex() {
return sex;
}

public void setSex(String sex) {
this.sex = sex;
}

public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}
}

3.userMapper.xml文件：

<?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.swc.base.dao.UserDAO">

<select id="getUserById" parameterType="Integer" resultType="com.swc.base.entity.User">
SELECT id,name,address,sex from tbl_user where id=#{id}
</select>

<select id="login" resultType="com.swc.base.entity.User" parameterType="com.swc.base.entity.User">
SELECT id,name,address,sex FROM tbl_user WHERE name = #{name,jdbcType=VARCHAR} and password=#{password,jdbcType=VARCHAR}
</select>
</mapper>

UserDAO .java

package com.swc.base.dao;

import com.swc.base.entity.User;

/**
* Created by chao on 2018-2-1.
*/
public interface UserDAO {

User getUserById(Integer id);

User login(User user);
}

UserService.java

package com.swc.base.service;

import com.swc.base.entity.User;

/**
* Created by chao on 2018-2-1.
*/
public interface UserService {

User login(User user);

User getUserById(Integer id);
}

UserServiceImpl.java

package com.swc.base.service.impl;

import com.swc.base.dao.UserDAO;
import com.swc.base.entity.User;
import com.swc.base.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
* Created by chao on 2018-2-1.
*/
@Service("userService")
public class UserServiceImpl implements UserService {

@Autowired
private UserDAO userDAO;

@Override
public User login(User user) {
return userDAO.login(user);
}

@Override
public User getUserById(Integer id) {
return userDAO.getUserById(id);
}
}

UserController.java

package com.swc.base.controller;

import com.swc.base.entity.User;
import com.swc.base.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;

/**
* Created by chao on 2018-2-1.
*/
@Controller
@RequestMapping("/user")
public class UserController {

@Autowired
private UserService userService;

@RequestMapping(value = "/getUser")
@ResponseBody
public User getUserById(){
Integer a = new Integer(1);
User user =userService.getUserById(a);
System.out.println(user.getName()+user.getAddress());
return user;
}
}

6.测试 TestMybatis.java

import com.swc.base.dao.UserDAO;
import com.swc.base.entity.User;
import org.apache.log4j.Logger;
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;

/**
* Created by chao on 2018-2-1.
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})
public class TestMybatis {
private static Logger logger= Logger.getLogger(TestMybatis.class);

@Autowired
private UserDAO dao;

@Test
public void testSelectUser() throws Exception {
Integer id = 1;
User user = dao.getUserById(id);
System.out.println(user.getName());
}

}

运行结果如下，成功获取数据，框架搭建完毕。
