Spring和JAXB集成的详细示例

Spring MVC Tiles示例

Spring提供了与apache tile框架的集成支持。因此，我们可以借助Spring Tile支持简单地管理Spring MVC应用程序的布局。

Spring MVC支持Tiles的优势

可重用性: : 我们可以在多个页面中重复使用单个组件，例如页眉和页脚组件。

集中式控件: 我们可以通过单个模板页面来控制页面的布局

易于更改布局: : 借助单个模板页面，我们可以随时更改页面的布局。因此，您的网站可以轻松采用新技术，例如引导程序，jQuery等。

Spring MVC Tiles示例

1、将依赖项添加到pom.xml文件。

pom.xml

 <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.1.1.RELEASE</version>
</dependency>
  <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
<dependency>  
    <groupId>javax.servlet</groupId>  
    <artifactId>servlet-api</artifactId>  
    <version>3.0-alpha-1</version>  
</dependency>
    <!-- https://mvnrepository.com/artifact/javax.servlet/jstl -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.tomcat/tomcat-jasper -->
<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-jasper</artifactId>
    <version>9.0.12</version>
</dependency>
 <!-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-jsp -->
<dependency>
    <groupId>org.apache.tiles</groupId>
    <artifactId>tiles-jsp</artifactId>
    <version>3.0.5</version>
</dependency>
    
    <!-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-servlet -->
<dependency>
    <groupId>org.apache.tiles</groupId>
    <artifactId>tiles-servlet</artifactId>
    <version>3.0.5</version>
</dependency>
    <!-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-core -->
<dependency>
    <groupId>org.apache.tiles</groupId>
    <artifactId>tiles-core</artifactId>
    <version>3.0.5</version>
</dependency>
   <!-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-el -->
<dependency>
    <groupId>org.apache.tiles</groupId>
    <artifactId>tiles-el</artifactId>
    <version>3.0.5</version>
</dependency>

2、创建bean类

Contact.java

package com.codebaoku.form;
public class Contact {
    private String firstname;
    private String lastname;
    private String email;
    private String telephone;
    
    public String getEmail() {
        return email;
    }
    public String getTelephone() {
        return telephone;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public void setTelephone(String telephone) {
        this.telephone = telephone;
    }
    public String getFirstname() {
        return firstname;
    }
    public String getLastname() {
        return lastname;
    }
    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }
    public void setLastname(String lastname) {
        this.lastname = lastname;
    }
    
}

3、创建控制器类

HelloWorldController.java

package com.codebaoku.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorldController {
    @RequestMapping("/hello")
    public String helloWorld(Model m) {
        String message = "Hello World, Spring MVC @ codebaoku";
        m.addAttribute("message", message);
        return "hello"; 
    }
}

ContactController.java

package com.codebaoku.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import com.codebaoku.form.Contact;
@Controller
@SessionAttributes
public class ContactController {
    @RequestMapping(value = "/addContact", method = RequestMethod.POST)
    public String addContact(@ModelAttribute("contact")  Contact contact, BindingResult result) {
        //write the code here to add contact
        return "redirect:contact.html";
    }
    
    @RequestMapping("/contact")
    public String showContacts(Model m) {
        m.addAttribute("command", new Contact());
        return "contact";
    }
}

4、在web.xml文件中提供控制器的条目

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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>SpringTiles</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <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>
    <url-pattern>*.html</url-pattern>
  </servlet-mapping>
</web-app>

5、在xml文件中定义Bean

spring-servlet.xml

<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/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<context:component-scan base-package="com.codebaoku.controller" />
<bean id="viewResolver" class="org.springframework.web.servlet.view.tiles3.TilesViewResolver"/>
<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
<property name="definitions">
<list>
<value>/WEB-INF/tiles.xml</value>
</list>
</property>
</bean>
</beans>

6、提供tile.xml文件

tiles.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
       "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
       "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">
<tiles-definitions>
    <definition name="base.definition"
        template="/WEB-INF/jsp/layout.jsp">
        <put-attribute name="title" value="" />
        <put-attribute name="header" value="/WEB-INF/jsp/header.jsp" />
        <put-attribute name="menu" value="/WEB-INF/jsp/menu.jsp" />
        <put-attribute name="body" value="" />
        <put-attribute name="footer" value="/WEB-INF/jsp/footer.jsp" />
    </definition>
    <definition name="contact" extends="base.definition">
        <put-attribute name="title" value="Contact Manager" />
        <put-attribute name="body" value="/WEB-INF/jsp/contact.jsp" />
    </definition>
    <definition name="hello" extends="base.definition">
        <put-attribute name="title" value="Hello Spring MVC" />
        <put-attribute name="body" value="/WEB-INF/jsp/hello.jsp" />
    </definition>
</tiles-definitions>

7、创建请求的页面

index.jsp

<a href="hello.html">Hello Spring</a> | 
<a href="contact.html">Contact</a>

8、创建其他视图组件

hello.jsp

<html>  
<head>  
    <title>Spring MVC Example</title>  
</head>  
<body>  
<h1>Welcome to Spring MVC</h1>  
    <p>Message is: ${message}</p>  
</body>  
</html>

contact.jsp

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>  
<html>  
<head>  
    <title>Spring Tiles Contact Form</title>  
</head>  
<body>  
<h2>Contact Manager</h2>  
<form:form method="post" action="addContact.html">  
  
    <table>  
    <tr>  
        <td><form:label path="firstname">First Name</form:label></td>  
        <td><form:input path="firstname" /></td>   
    </tr>  
    <tr>  
        <td><form:label path="lastname">Last Name</form:label></td>  
        <td><form:input path="lastname" /></td>  
    </tr>  
    <tr>  
        <td><form:label path="lastname">Email</form:label></td>  
        <td><form:input path="email" /></td>  
    </tr>  
    <tr>  
        <td><form:label path="lastname">Telephone</form:label></td>  
        <td><form:input path="telephone" /></td>  
    </tr>  
    <tr>  
        <td colspan="2">  
            <input type="submit" value="Add Contact"/>  
        </td>  
    </tr>  
</table>    
      
</form:form>  
</body>  
</html>
