首先在Myeclipse10里自动导入spring3.0
然后我们继续。。
1，web.xml文件的配置
代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name></display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:bean*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name> <!-- 这里在配成spring,下边也要写一个名为spring-servlet.xml的文件，主要用来配置它的controller -->
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
2，实体类文件 所在目录为com.mvc.domain
代码如下：
package com.mvc.domain;
import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "study")
public class Student {
@Id
@Basic(optional = false)
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", nullable = false)
private int id;
@Column(name = "name")
private String name;
@Column(name = "address")
private String address;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
3，创建公共Dao接口
package com.mvc.dao;
import java.util.List;
public interface BaseDao {
public List<Object> getList();
public void add(Object obj);
public void update(Object obj);
public void delete(int id);
public Object getById();
}
4，創建學生Dao類 實現BaseDao
package com.mvc.dao;
import java.util.ArrayList;
import java.util.List;
import com.mvc.domain.Student;
public class StudentDao implements BaseDao {
private Student student;
@Override
public List<Object> getList() {
List<Object> list = new ArrayList<Object>();
student.setAddress("陕西省");
student.setName("ni");
student.setId(1);
list.add(student);
return list;
}
@Override
public void add(Object obj) {
System.out.println(obj.getClass().getName());
}
@Override
public void update(Object obj) {
}
@Override
public void delete(int id) {
}
@Override
public Object getById() {
return null;
}
public Student getStudent() {
return student;
}
public void setStudent(Student student) {
this.student = student;
}
}
5，創建公共Servie類 BaseService
代碼和BaseService基本一致
package com.mvc.service;
import java.util.List;
public interface BaseService {
public List<Object> getList();
public void add(Object obj);
public void update(Object obj);
public void delete(int id);
public Object getById();
}
6，創建Service的實現類 實現BaseService接口
package com.mvc.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.mvc.dao.StudentDao;
import com.mvc.service.BaseService;
@Service
public class StudentServiceImpl implements BaseService {
@Autowired
private StudentDao studentDao;
@Override
public List<Object> getList() {
return studentDao.getList();
}
@Override
public void add(Object obj) {
studentDao.add(obj);
}
@Override
public void update(Object obj) {
}
@Override
public void delete(int id) {
}
@Override
public Object getById() {
return null;
}
public StudentDao getStudentDao() {
return studentDao;
}
public void setStudentDao(StudentDao studentDao) {
this.studentDao = studentDao;
}
}
7，創建控制器的公共類
package com.mvc.dao;
import javax.servlet.http.HttpServletRequest;
import org.springframework.ui.ModelMap;
public interface BaseController {
public String add(HttpServletRequest request, ModelMap modelMap);
public String update(HttpServletRequest request, ModelMap modelMap);
public String delete(HttpServletRequest request, ModelMap modelMap);
public String get(HttpServletRequest request, ModelMap modelMap);
public String getList(HttpServletRequest request, ModelMap modelMap);
}
8,創建控制器的實現類
package com.mvc.controller;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import com.mvc.dao.BaseController;
import com.mvc.domain.Student;
import com.mvc.service.impl.StudentServiceImpl;
@Controller
@RequestMapping("/student.do")
public class StudentController implements BaseController {
@Autowired
private StudentServiceImpl studentService;
@Override
@RequestMapping(params = "method=add")
public String add(HttpServletRequest request, ModelMap modelMap) {
Student student = new Student();
student.setId(1);
student.setName("shi");
student.setAddress("shanxishengweinanshifupingxianqicunxianganlecunhuyaozu");
studentService.add(student);
modelMap.put("message", "Wo! It's a Successly");
return "index";
//返回值index 代表的就是 控制器会根据返回值然后自动寻找index.jsp
}
@Override
@RequestMapping(params = "method=update")
public String update(HttpServletRequest request, ModelMap modelMap) {
return null;
}
@Override
@RequestMapping(params = "method=delete")
public String delete(HttpServletRequest request, ModelMap modelMap) {
return null;
}
@Override
@RequestMapping(params = "method=get")
public String get(HttpServletRequest request, ModelMap modelMap) {
return null;
}
@Override
@RequestMapping(params = "method=getList")
public String getList(HttpServletRequest request, ModelMap modelMap) {
List<Object> list = studentService.getList();
// request.setAttribute("list", list);
modelMap.put("list", list);
return "my";
}
public StudentServiceImpl getStudentService() {
return studentService;
}
public void setStudentService(StudentServiceImpl studentService) {
this.studentService = studentService;
}
}
9，創建bean.xml spring的容器
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"
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
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<context:annotation-config />
<context:component-scan base-package="com.mvc" /> <!-- 自动扫描所有注解该路径 -->
<bean id="student" class="com.mvc.domain.Student" />
<bean id="studentDao" class="com.mvc.dao.StudentDao">
<property name="student" ref="student" />
</bean>
<bean id="studentService" class="com.mvc.service.impl.StudentServiceImpl">
<property name="studentDao" ref="studentDao" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<tx:annotation-driven mode="aspectj" />
<aop:aspectj-autoproxy />
</beans>
10，創建spring-servlet.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:p="http://www.springframework.org/schema/p"
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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<!-- 把标记了@Controller注解的类转换为bean -->
<context:component-scan base-package="com.mvc.controller" />
<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/view/" p:suffix=".jsp" />
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
p:defaultEncoding="utf-8" />
</beans>
11，最後就是spring mvc中的view視圖了
在WEB-INF下創建view文件夾
創建my.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My.jsp</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<body>
This is my first Spring MVC Test page!
<br>
<c:forEach items="${list}" var="student">
${student.id}
${student.name}
${student.address}
<br><br>
</c:forEach>
</body>
</html>
創建一個index.jsp
代碼如下：
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>index.jsp]</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
</head>
<body>
${message}
</body>
</html>
再創建一個添加的一個視圖頁
Add.jsp
代碼如下：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>A add page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
</head>
<body>
<form action="student.do?method=add" method="post">
id:<input type="text" name="id"><br> <br> name:<input
type="text" name="name"><br> <br> address:<input
type="text" name="address"><br> <br> <input
type="submit" value="提交"><br> <br>
</form>
</body>
</html>
Spring Mvc搭建好了，可以正常使用了，比起Struts2，那真算方便多了！
不用在struts2.xml里進行一個一個的配置
只需要在Spring Mvc里進行註解配置 就可以了！
