maven学习笔记3使用maven创建ssm 测试项目

在pom中增加 spring mvc的依赖信息

完成spring配置文件的编写

  
<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:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

    default-lazy-init="true">  
    
    <context:component-scan base-package="com.mvc" />
    
    <mvc:annotation-driven >mvc:annotation-driven>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    <context:property-placeholder location="classpath:jdbc.properties" />
    
 	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
 		<property name="driverClassName" value="${jdbc.driver}">property>

 	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
 		<property name="basePackage" value="com.mvc.dao">property>
 	bean> 
    beans>

在web.xml 加载spirng的核心控制器

<servlet>
  	<servlet-name>springmvcservlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
  	<init-param>
  		<param-name>contextConfigLocationparam-name>
  		<param-value>classpath:springmvc.xmlparam-value>
  	init-param>
  servlet>
  <servlet-mapping>
  	<servlet-name>springmvcservlet-name>
  	<url-pattern>/url-pattern>
  servlet-mapping>

编写测试代码 java

• 控制层

   @ResponseBody
   @RequestMapping("student_list")
   public List<Student> student_list(Model model){
   	return pd.slist();
   }

• 数据访问层

public interface PageDao {

  @Select("select * from student")
  public List<Student> slist();
}

• 实体对象

public class Student {
  
  String id;
  String name;
  String age;
  String sex;

编写测试页面

<%@ 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>
${name}
</body>
</html>

访问测试页面ok
