1.Spring的Service配置
在src/main/java下创建service包
在src/main/resources/spring下创建spring-service.xml配置文件
<?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/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<!-- 扫描service包下所有使用注解的类型 -->
<context:component-scan base-package="org.first.service"/>
<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 配置基于注解的声明式事务，默认使用注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
使用注解实现自动装填
在service包下创建UserService.java接口：
public interface UserService {
List<User> getAll();
int addUser(User user);
}
在service包下创建impl包，再在impl包下实现UserService接口
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
public List<User> getAll() {
return userDao.queryAll(0,4);
}
public int addUser(User user) {
return userDao.insertUser(user);
}
}
上面实现类使用@Service与@Autowired注解
使用Junit4测试Service接口
测试之前需要先配置logback配置文件，先进入logback官网
点击打开链接 ，在这里我们选择最简单的配置
在scr/maim/resources下新建logback.xml配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT" />
</root>
</configuration>
Junit测试
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({
"classpath:spring/spring-dao.xml",
"classpath:spring/spring-service.xml"})
public class UserServiceTest {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private UserService userService;
@Test
public void getAll() throws Exception {
List<User> list = userService.getAll();
logger.info("list={}", list);
}
@Test
public void addUser() throws Exception {
User user = new User();
user.setName("小强");
user.setSex(1);
int result = userService.addUser(user);
logger.info("" + result);
}
}
2.Spring的Web配置
在配置web之前，我们需要知道Restful：一种URI表述方式
Restful规范
GET
->
查询操作
POST
->
添加 / 修改操作
PUT
->
修改操作
DELETE-
->
删除操作
URL设计：
/模块/资源/{标示}/集合1/...
接下来开始配置SpringMVC框架
1）配置src/main/webapp/WEB-INF/web.xml
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
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">
<servlet>
<servlet-name>first-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring-*.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>first-dispatcher</servlet-name>
<!-- 默认匹配所有的请求 -->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
2)在src/main/resources/spring下创建spring-web.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<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"
xmlns="http://www.springframework.org/schema/beans"
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.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 配置SpringMVC -->
<!-- 1：开启SpringMVC注解模式 -->
<mvc:annotation-driven/>
<!-- 2：静态资源默认servlet配置 -->
<mvc:default-servlet-handler/>
<!-- 3：配置jsp 显示ViewResolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!-- 4：扫描web相关的bean -->
<context:component-scan base-package="org.first.web"/>
</beans>
配置完成后，在src/main/java下创建web包
创建UserController.java
@Controller
//URL设计： /模块/资源/{标示}/集合1/...
@RequestMapping("/user") //url:/模块
public class UserController {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private UserService userService;
@RequestMapping(value = "/list",method = RequestMethod.GET) // /资源
public String list(Model model){
List<User> list=userService.getAll();
model.addAttribute("list",list);
return "list";// /WEB-IBF/jsp/"list".jsp
}
@RequestMapping(value = "/addUser",method = RequestMethod.POST)
public String addUser(User user,Model model){
int result=userService.addUser(user);
model.addAttribute("result",result);
return "redirect:list";
}
}
3.JSP页面显示
我们使用BootStrap来写jsp
在src\main\webapp\WEB-INF\jsp\common下创建两个jsp，分别放我们的用到的jsp头与标签
head.jsp
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- 引入 Bootstrap -->
<link href="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/css/bootstrap.min.css"
rel="stylesheet">
<!-- HTML5 Shim 和 Respond.js 用于让 IE8 支持 HTML5元素和媒体查询 -->
<!-- 注意： 如果通过 file:// 引入 Respond.js 文件，则该文件无法起效果 -->
<!--[if lt IE 9]>
<script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script>
<script src="https://oss.maxcdn.com/libs/respond.js/1.3.0/respond.min.js"></script>
<![endif]-->
tag.jsp
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
在src\main\webapp\WEB-INF\jsp\下创建list.jsp
<%@page contentType="text/html; charset=UTF-8" language="java" %>
<%-- 引入jstl--%>
<%@include file="common/tag.jsp" %>
<!DOCTYPE html>
<html>
<head>
<title>用户列表页</title>
<%@include file="common/head.jsp" %>
</head>
<body style="margin-top: 10px">
<form action="/user/addUser" method="post" class="form-inline" role="form">
<div class="container">
<div class="panel panel-default">
<div class="panel-heading text-left">
<h4>新增用户</h4>
</div>
<div class="form-group">
<label for="name" class="control-label">用户名：</label>
<input type="text" class="form-control" id="name" name="name" placeholder="请输入名称">
</div>
<div class="form-group">
<label class="control-label">性别：</label>
<label class="checkbox-inline">
<input type="radio" name="sex" value="1" checked>男
</label>
<label class="checkbox-inline">
<input type="radio" name="sex" value="0">女
</label>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">提交</button>
</div>
</div>
</div>
</div>
</form>
<%--页面显示部分--%>
<div class="container">
<div class="panel panel-default">
<div class="panel-heading text-center">
<h2>用户列表</h2>
</div>
<div class="panel-body">
<table class="table table-hover">
<thead>
<tr>
<th>id</th>
<th>名称</th>
<th>性别</th>
<th>创建时间</th>
</tr>
</thead>
<tbody>
<c:forEach var="list" items="${list}">
<tr>
<td>${list.id}</td>
<td>${list.name}</td>
<td>
<c:if test="${1==list.sex}">男生</c:if>
<c:if test="${0==list.sex}">女生</c:if>
</td>
<td>
<fmt:formatDate value="${list.createTime}" pattern="yyyy-MM-dd HH:mm:ss"/>
</td>
</tr>
</c:forEach>
</tbody>
</table>
</div>
</div>
</div>
</body>
<!-- jQuery文件。务必在bootstrap.min.js 之前引入 -->
<script src="http://cdn.static.runoob.com/libs/jquery/2.1.1/jquery.min.js"></script>
<!-- 最新的 Bootstrap 核心 JavaScript 文件 -->
<script src="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</html>
注：我在调试的时候发现插入数据库的数据发生中文乱码问题
解决方法：在web.xml中加入以下代码
<!-- 强制页面utf-8 -->
<filter>
<filter-name>encodingFilter</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>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
至此，所有配置已经完成，这篇《在IntelliJ IDEA上使用Maven搭建SSM框架》是我在看了慕课网的maven管理利器和秒杀案例再加上自己百度，一字一句打出来的，把自己所学梳理了一遍，各种相关的配置还是略为简单，还是要多看看框架源码
