之前工作有用到SpringMVC,最近想整理个例子,用于归纳总结,及方便新手学习。查看了网上的不少例子，都是不完整或者用不了的，爬了不少坑，终于花两天时间调通了这个例子，并花了一晚上写完这篇文章。
关于spring相关概念及SSM框架，直接贴代码，理论的不多赘述了。项目代码结构请参照文章结尾。
一、软件准备:
1.1 idea下载地址(IntelliJ IDEA 2018.1.6 x64专业版):https://www.jetbrains.com/idea/download/#section=windows
1.2 easyUI下载地址(jquery-easyui-1.5.5.4):http://www.jeasyui.com/download/v154.php
二、IDEA 开发环境搭建部署及建立 maven web项目
参考文章:https://blog.csdn.net/zwjzqqb/article/details/79040383
注意:1.创建maven web项目 没有src webapp文件夹 原因:maven仓库调用外网
建议使用maven私服库: maven安装地址 下更改setting.xml
<!-- 阿里云仓库 -->
<mirrors>
<mirror>
<id>alimaven</id>
<mirrorOf>central</mirrorOf>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
</mirror>
<!-- 中央仓库 -->
<mirror>
<id>repo</id>
<mirrorOf>central</mirrorOf>
<name>Human Readable Name for this Mirror.</name>
<url>http://repo1.maven.org/maven2/</url>
</mirror>
</mirrors>创建maven web项目成功。
项目结构如下:
在src/main下新增java resources文件夹 分别设置为 sources resources
新增src/test/java 设置为tests
项目结构修改如下:
三、SSM框架整合
Spring 4.0.2 RELEASE
Spring MVC 4.0.2 RELEASE
MyBatis 3.2.6
3.1、Maven引入需要的JAR包
pom.xml文件

<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>3.2、Spring与MyBatis的整合
3.2.1、建立JDBC属性文件
mysql数据库连接: 数据库名:zhq ?后面的 防止中文乱码
jdbc.properties （文件编码修改为 utf-8 ）
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/zhq?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true
username=root
password=
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=600003.2.2、建立spring-mybatis.xml配置文件
之前dao所在包名错误 导致一直报错
<?xml version="1.0" encoding="UTF-8"?>

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>3.2.3、Log4j的配置
log4j.rootLogger=debug,stdout,logfile及后面4行 使得输出执行的sql语句 很有用
log4j.rootLogger=debug,stdout,logfile
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout
log4j.appender.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.File=E:/Work/WorkSpaces/MyEclipse 10/mavenDemo/logs/ssm.log

log4j.appender.logfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %F %p %m%n
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG3.2.4、JUnit测试
3.2.4.1、创建测试表 数据
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for users
-- ----------------------------
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_name` varchar(32) DEFAULT NULL,
`password` varchar(64) DEFAULT NULL,
`age` int(4) DEFAULT NULL,
`true_name` varchar(32) DEFAULT NULL,
`email` varchar(64) DEFAULT NULL,
`phone` varchar(64) DEFAULT NULL,
`role_name` varchar(32) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of users
-- ----------------------------
INSERT INTO `users` VALUES ('1', '测试', 'sfasgfaf', '24', 'ffff', 'aaa', '18855633', '2');
INSERT INTO `users` VALUES ('2', 'zhq', 'zhq', '27', 'ffggg', 'gga', '2365', 'fsdfsd');
INSERT INTO `users` VALUES ('3', 'hello', 'hello', '22', 'fsdfsd', 'fdf', '222', 'sdfsdf');
INSERT INTO `users` VALUES ('5', '测试1', '123', '23', '庄', '[email protected]', '1884553', 'sales executive');3.2.4.2、利用MyBatis Generator自动创建代码
参考文章:http://blog.csdn.net/zhshulin/article/details/23912615
生成:UserDao.java UserDao.xml User.java
userDao.xml生成后需要自己修改 namespace parameterType
UserDao.java
package com.zhq.dao;
import com.zhq.pojo.User;
import java.util.List;
import java.util.Map;
/**
* 用户DAO接口
* @author Administrator

public interface UserDao {
/**

public int delete(int id);
/**

public int update(User user);
/**

public int add(User user);
/**

public List<User> find(Map<String,Object> map);
/**

public Long getTotal(Map<String,Object> map);
/**

User.java
package com.zhq.pojo;
import java.io.Serializable;
/**

public class User implements Serializable {
private static final long serialVersionUID = 1L;

this.phone = phone;
}
public String getRoleName() {
return roleName;
}
public void setRoleName(String roleName) {
this.roleName = roleName;
}
}
3.2.4.3、建立Service接口和实现类
UserService.java
package com.zhq.service;
import com.zhq.pojo.User;
import java.util.List;
import java.util.Map;
public interface UserService {
public int delete(int id);
public int update(User user);
public int add(User user);
public List<User> find(Map<String,Object> map);
public Long getTotal(Map<String,Object> map);
public User getUserById(int id);
}
UserServiceImpl.java
package com.zhq.service.impl;
import com.zhq.dao.UserDao;
import com.zhq.pojo.User;
import com.zhq.service.UserService;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.List;
import java.util.Map;
@Service(value="com.zhq.userService.impl")
public class UserServiceImpl implements UserService {
@Resource
private UserDao userDao;
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
@Override
public int delete(int id) {
return userDao.delete(id);
}
@Override
public int update(User user) {
return userDao.update(user);
}
@Override
public int add(User user) {
return userDao.add(user);
}
@Override
public List<User> find(Map<String, Object> map) {
return userDao.find(map);
}
@Override
public Long getTotal(Map<String, Object> map) {
return userDao.getTotal(map);
}
public User getUserById(int id){
return userDao.getUserById(id);
}
}
3.2.4.4、建立测试类
import com.alibaba.fastjson.JSON;
import com.zhq.pojo.User;
import com.zhq.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;
/**
* Created by zhqPc on 2018/7/19.
*/
@RunWith(SpringJUnit4ClassRunner.class) //表示继承了SpringJUnit4ClassRunner类
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})
public class TestMyBatis {
private static Logger logger = Logger.getLogger(TestMyBatis.class);
// private ApplicationContext ac = null;
@Resource
private UserService userService;
// @Before
// public void before() {
// ac = new ClassPathXmlApplicationContext("applicationContext.xml");
// userService = (UserService) ac.getBean("userService");
// }
@Test
public void test1() {
User user = userService.getUserById(1);
// System.out.println(user.getUserName());
// logger.info("值："+user.getUserName());
logger.info(JSON.toJSONString(user));
}
}测试结果:
3.3、整合SpringMVC
上面已经完成了2大框架的整合，SpringMVC的配置文件单独放，然后在web.xml中配置整合。
3.3.1、配置spring-mvc.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:p="http://www.springframework.org/schema/p"

<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.zhq.controller" />

<ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->
</list>
</property>
</bean>
<!-- 定义跳转的文件的前后缀 ，视图模式配置-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面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 -->
<property name="prefix" value="/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->
<bean id="multipartResolver"

<!-- 内存中的最大值 -->
<property name="maxInMemorySize" value="40960" />
</bean>
</beans>3.3.2、配置web.xml文件
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<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"
version="3.0">

</context-param>
<!-- 编码过滤器 -->

<url-pattern>*.do</url-pattern>
</filter-mapping>
<!-- Spring监听器 -->

</listener>
<!-- 防止Spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<!-- Spring MVC servlet -->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>

<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
</web-app>*.do 用于控制器调用
3.3.3、测试
至此已经完成了SSM三大框架的整合了，接下来测试一下。
3.3.3.1、新建jsp页面
上传文件file.jsp页面

3.3.3.3、其它工具类
分页Model类PageBean.java
package com.zhq.util;
/**
* 分页Model类
* @author Administrator
*
*/
public class PageBean {
private int page; // 第几页
private int pageSize; // 每页记录数
private int start; // 起始页
public PageBean(int page, int pageSize) {
super();
this.page = page;
this.pageSize = pageSize;
}
public int getPage() {
return page;
}
public void setPage(int page) {
this.page = page;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public int getStart() {
return (page-1)*pageSize;
}
}
用于返回json数据ResponseUtil.java
package com.zhq.util;
import javax.servlet.http.HttpServletResponse;
import java.io.PrintWriter;
/***
* 主要用于返回json数据
* @author Administrator
*/
public class ResponseUtil {
public static void write(HttpServletResponse response,Object object)throws Exception{
response.setContentType("text/html;charset=utf-8");
PrintWriter out=response.getWriter();
out.println(object);
out.flush();
out.close();
}
}
字符串工具类StringUtil.java如下:
package com.zhq.util;
/***
* 字符串工具类
* @author Administrator
*
*/
public class StringUtil {
/**
* 判断是否是空
* @param str
* @return
*/
public static boolean isEmpty(String str){
if(str==null||"".equals(str.trim())){
return true;W
}else{
return false;
}
}
/**
* 判断是否不是空
* @param str
* @return
*/
public static boolean isNotEmpty(String str){
if((str!=null)&&!"".equals(str.trim())){
return true;
}else{
return false;
}
}
/**
* 格式化模糊查询
* @param str
* @return
*/
public static String formatLike(String str){
if(isNotEmpty(str)){
return "%"+str+"%";
}else{
return "";
}
}
/**
* 获取非空值
* @param str
* @return
*/
public static String getValue(String str){
if (isEmpty(str)){
return "";
}else{
return str;
}
}
}
