SSM(SpringMVC Spring Mybatis)框架整合搭建
2024-08-21 00:56:23
1、新建一个web工程。
2、首先看一下整体的框架结构：
3、将ssm框架搭建所需要的jar包复制到lib目录下
3、需要配置各个配置文件。
1）配置web.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
http://www.springmodules.org/schema/cache/springmodules-cache.xsd
http://www.springmodules.org/schema/cache/springmodules-encache.xsd"
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="WebApp_ID" version="3.0">
<display-name>qzone</display-name>
<welcome-file-list>
<welcome-file>user.jsp</welcome-file>
</welcome-file-list>
<!-- spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext.xml</param-value>
</context-param>
<!-- spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> <!-- 添加springmvc的支持 -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
2）在resource/spring下创建applicationContext.xml配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</tx:advice> </beans>
3)在resource/spring下创建spring-mvc.xml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:p="http://www.springframework.org/schema/p"

<!-- 指定注解要扫描的包 -->
<context:component-scan base-package="com.ekingwin.bas.cloud.user.web"></context:component-scan>
<!-- 视图解析器，自动加上前缀和后缀 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean> <!-- Spring 来扫描指定包下的类，并注册被@Component，@Controller，@Service，@Repository等注解标记的组件 -->
<mvc:annotation-driven /> </beans>
4）在resource/mybatis下创建mybatis-config.xml配置文件：
<?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>
<!-- 批量定义别名，使得com.etc.entity包下的所有bean都使用别名（别名就是类名，首字母大写或小写都可以） -->
<typeAliases>
<package name="com.ekingwin.bas.cloud"/>
</typeAliases>
</configuration>
5）在resource下创建dbconfig.properties文件：
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm
jdbc.username=root
jdbc.password=123456
6）在resource下创建log4j.properties文件：
<span style="font-size:18px;">log4j.rootLogger=info,appender1,appender2
log4j.appender.appender1=org.apache.log4j.ConsoleAppender
log4j.appender.appender2=org.apache.log4j.FileAppender
log4j.appender.appender2.File=D:/logFile.txt

log4j.appender.appender2.layout=org.apache.log4j.TTCCLayout</span>
7）在resource/mapper下创建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.ekingwin.bas.cloud.user.dao.IUserDao">
<!-- <resultMap type="User" id="UserResult">
<result property="id" column="id"/>
<result property="username" column="username"/>
<result property="password" column="password"/>
</resultMap> -->
<!-- <select id="login" parameterType="User" resultMap="UserResult">

System.out.println("12313247092137498123");
return users;
} @Override
public String getmessage(UserDto user) throws UserException {
// TODO Auto-generated method stub String username = user.getUsername();
List<Map<String, Object>> list = userDao.getInfo(username);
System.out.println(list);
System.out.println("123123");
return null;
}
} //@Service
//public class UserServiceImpl implements IUserService{
//
//
// @Autowired
// private UserDao userDao;
//
//
// @Override
// public String getmessage(UserDto user) throws UserException {
//// String username = user.getUsername();
//// String username=user.getParameter("username");

</body>
<!-- <body>
<div>
<button id="subBtn">测试</button>
</div>
<script type= "text/javascript">
$().ready(function(){
document.getElementById("subBtn").onclick = function () {
request3();
};
//=========================请求方式3================//
var url = "/SSM/user/login.do";
var data = {"username":"小名" };
var request3 = function (){
$.ajax({
contentType: 'application/json;charset=UTF-8',
url: url,
type: 'POST',
data: JSON.stringify(data),
dataType: 'json'
