搭建步骤
一、创建Maven项目
具体操作如下图
新建好的项目会有报错提示,别着急,在项目上右键选择 Java EE Tools > Generate Deployment Descriptor Stub
接下来在项目上右键选择最后一项 Properties > Project Facets
到这里一个Maven的Web项目就创建好了
二、在pom.xml中添加依赖包

三、配置web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<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"
id="WebApp_ID" version="3.1">
<display-name>ssm</display-name>
<!-- 过滤器解决中文乱码问题、强制编码 UTF-8 -->
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>

</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置 springMVC 基本配置 -->

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- Bootstraps the root web application context before servlet initialization -->

</listener>
<!-- 配置欢迎页 -->
<welcome-file-list>
<welcome-file>views/index.jsp</welcome-file>
</welcome-file-list>
</web-app>
四、在src/main/resources下创建spring配置文件
创建applicationContext.xml配置如下
<?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.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
<!-- 自动扫描指定目录,将控制器加载到bean -->
<context:component-scan base-package="com.frame" />
<!-- 配置 druid 数据源 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<!-- 基本属性 url、user、password、driverClass -->
<property name="username" value="root" />
<property name="password" value="root" />
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://192.168.0.200:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false" />
</bean>
<!-- 配置 sessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations">
<list>
<value>classpath:com/frame/**/*Mapper.xml</value>
<value>classpath:mybatis/**/*Mapper.xml</value>
</list>
</property>
</bean>
<!-- 配置 sqlSessionTemplate 持久化模板 -->
<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg ref="sqlSessionFactory" />
</bean>
<!-- 配置事物管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 配置事物传播行为 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true" />
<tx:method name="find*" read-only="true" />
<tx:method name="select*" read-only="true" />
<tx:method name="*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>
<!-- 配置事物切入点 -->
<aop:config>
<aop:pointcut expression="execution(* com.frame.service.*.*(..))" id="pointCut" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut" />
</aop:config>
<!-- 开始声明式事务(事物注解) -->
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>
创建spring-mvc.xml配置如下
<?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"
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-4.3.xsd">
<!-- 自动将控制器加载到bean -->
<context:component-scan base-package="com.frame.controller" />
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/views/" />
<property name="suffix" value=".jsp" />
<!-- 可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑 -->
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
</bean>
<!-- 返回json 需导入 jackson-annotations.jar,jackson-core.jar,jackson-databind.jar -->
<!-- 通过处理器映射DefaultAnnotationHandlerMapping来开启支持@Controller注解 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
<!-- 通过处理器适配器AnnotationMethodHandlerAdapter来开启支持@RequestMapping注解 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<!-- 配置返回字符串编码 -->
<bean
class="org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html; charset=UTF-8</value>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 配置 json 转换器 -->
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html; charset=UTF-8</value>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
</list>
</property>
</bean>
</beans>
五、在src/main/resources下创建mybatis/**/*Mapper.xml模板
用于撰写mybatis执行sql的语句
<?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.frame.mapper.DemoMapper">
<select id="getTest" resultType="java.util.Map">
SELECT * FROM TB_TEST
</select>
</mapper>
五、在src/main/java下创建com.frame.*测试类
创建service接口
package com.frame.service;
public interface DemoService {
void test();
}
创建service业务层实现类
package com.frame.service.impl;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.frame.service.DemoService;
@Service("demoService")
public class DemoServiceImpl implements DemoService {
@Autowired
private SqlSessionTemplate sqlSessionTemplate;
// mybatis sql模板的命名空间
private static final String NAMESPACE = "com.frame.mapper.DemoMapper";
@Override
public void test() {
System.out.println("返回查询结果集 -> " + sqlSessionTemplate.selectList(NAMESPACE + ".getTest")); // 查询结果集
}
}
创建controller控制器
package com.frame.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.frame.service.DemoService;
@Controller
public class DemoController {
@Autowired
private DemoService demoService;
@RequestMapping("/hello")
public String hello() {
System.out.println("执行hello控制器方法");
// 调用业务层执行查询操作
demoService.test();
return "hello";
}
}
六、在webapp下创建views/*.jsp页面
创建index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
This is index page.
</body>
</html>
创建hello.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>Hello World!</h1>
</body>
</html>
七、部署项目并启动服务(Jetty/Tomcat)
服务启动成功后输入地址http://localhost:8888/ssm/hello进行测试,页面将展示Hello World!字样,控制台输入如下信息
执行hello控制器方法
返回查询结果集 -> [{ID=1ba6d11d2639401ebf63c00c5ae7c2a0, NAME=SSM, TYPE=FRAME}]
到此整个框架就搭建完成了,接下来即可进入开发阶段,如果感觉不错请分享出去。
