最近因为公司没事干自己学习搭建框架,因以前所接触的都是金融类项目,所用框架都是ssh;springMVC对于本人来说还是比较陌生的;所以就想通过搭建框架来认识它;
第一步:准备jar包;(这些jar都是我从网上东拼西凑合在一起的,有些可能是多余的)
jar包目录:
第二步:配置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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 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>test_005</display-name> <!--不初始化servlet.xml;系统会自动在WEB-INF下面找 servlet-name 加 -servlet.xml --> <servlet> <servlet-name>springTest</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <description>核心配置</description> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/springTest-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 跳转路径设置 --> <servlet-mapping> <servlet-name>springTest</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <!-- 配置编码转换 UTF-8 --> <filter> <filter-name>encodeingFilter</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>encodeingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置异常跳转页面 --> <error-page> <error-code>404</error-code> <location>/err/404.jsp</location> </error-page> <error-page> <error-code>500</error-code> <location>/err/500.jsp</location> </error-page> <error-page> <error-code>401</error-code> <location>/err/401.jsp</location> </error-page> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
第三步:web.xml文件配置完成之后,开始配置-servlet.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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 对相关包下面的类进行扫描,进行自动注入 --> <context:component-scan base-package="com.test.controller,com.test.service"/> <!-- 进行请求映射 controller --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> <!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
4、servlet配置完成之后开始编写controller和service ,jsp开始进行测试;
controller类:
package com.test.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import com.test.service.TestService; @Controller @RequestMapping(value="/test/controller") public class TestController { @Autowired private TestService testService; @RequestMapping(value="test1") public String test1(Model model){ model.addAttribute("test1", testService.test1()); return "test1"; } }service类:
package com.test.service; import org.springframework.stereotype.Service; @Service public class TestService { public String test1(){ return "嘿嘿嘿...可以了!!!"; } }
以下均为jsp页面body
index.jsp页面:
<h4>开始测试:</h4> <a href="test/controller/test1">去test1页面</a>404.jsp页面:
<h4>路径出错鸟!!!!</h4>
test1.jsp页面:
<h4>我是test1</h4> ${test1 }放入tomcat里面,开始运行;
OK运行完成没有问题;
最简单的地方搞好了;现在开始配置数据库连接,dao等等信息;
第四步:将web.xml文件添加 spring监听,也就是项目启动时自动读取上下文;
<!-- 配置监听,读取上下文 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:resource/applicationContext-*.xml</param-value> </context-param>现在开始写配置文件:jdbc、tx等等信息;
applicationContext-dao.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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="myTestMapper" parent="baseMapper"> <property name="mapperInterface" value="com.test.dao.MyTestMapper" /> </bean> </beans>
applicationContext-jdbc.xml:

applicationContext-resource.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:jee="http://www.springframework.org/schema/jee" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/> <property name="ignoreResourceNotFound" value="true" /> <property name="locations"> <list> <value>classpath*:resource/mysql-jdbc.properties</value> </list> </property> </bean> </beans>
applicationContext-tx.xml:

mysql-jdbc.properties:
jdbc_driver=com.mysql.jdbc.Driver jdbc_url=jdbc:mysql://127.0.0.1:3306/test?characterEncoding=UTF-8 jdbc_username=test jdbc_password=test
dao类:
package com.test.dao; public interface MyTestMapper { List<MyTest> selectByMyTestInfo(); }
service类:
package com.test.service; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.test.dao.MyTestMapper; import com.entity.MyTest; @Service public class TestService { @Autowired <span style="white-space:pre"> </span>private MyTestMapper myTestMapper; public String test1(){ return "嘿嘿嘿...可以了!!!"; } <span style="white-space:pre"> </span>public List<MyTest> selectByMyTestInfo(){ return myTestMapper.selectByMyTestInfo(); } }
mapper.xml配置
<?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.dao.MyTestMapper" > <resultMap id="BaseResultMap" type="com.entity.MyTest" > <id column="ID" property="id" jdbcType="BIGINT" /> <result column="txt" property="txt" jdbcType="VARCHAR" /> <result column="desc" property="desc" jdbcType="VARCHAR" /> </resultMap> <sql id="Base_Column_List" > id, txt, desc </sql> <select id="selectByMyTestInfo" resultMap="BaseResultMap"> select * from myTest </select> </mapper>
controller类添加
<span style="white-space:pre"> </span>@RequestMapping(value="method1") public String show(Model model){ List<MyTest> list=myService.selectByMyTestInfo(); StringBuffer sb=new StringBuffer(); for(MyTest my: list){ sb.append("id="+my.getId()+"; txt="+my.getTxt()+"; desc="+my.getDesc()+"<br/>"); } model.addAttribute("sbToString", sb); return "show"; }
