Spring MVC - Generate XML Example

以下示例展示如何使用 Spring Web MVC 框架生成 XML。首先,让我们有一个正在运行的 Eclipse IDE,并坚持以下步骤以使用 Spring Web 框架开发一个可动态创建表单的 Web 应用程序。

The following example shows how to generate XML using the Spring Web MVC Framework. To begin with, let us have a working Eclipse IDE in place and stick to the following steps to develop a Dynamic Form based Web Application using the Spring Web Framework.

Step

Description

1

Create a project with a name TestWeb under a package com.tutorialspoint as explained in the Spring MVC - Hello World chapter.

2

Create Java classes User and UserController under the com.tutorialspointpackage.

3

The final step is to create the content of the source and configuration files and export the application as explained below.

User.java

package com.tutorialspoint;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "user")
public class User {
   private String name;
   private int id;
   public String getName() {
      return name;
   }
   @XmlElement
   public void setName(String name) {
      this.name = name;
   }
   public int getId() {
      return id;
   }
   @XmlElement
   public void setId(int id) {
      this.id = id;
   }
}

UserController.java

package com.tutorialspoint;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/user")
public class UserController {

   @RequestMapping(value="{name}", method = RequestMethod.GET)
   public @ResponseBody User getUser(@PathVariable String name) {

      User user = new User();

      user.setName(name);
      user.setId(1);
      return user;
   }
}

TestWeb-servlet.xml

<beans xmlns = "http://www.springframework.org/schema/beans"
   xmlns:context = "http://www.springframework.org/schema/context"
   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
   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
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context-3.0.xsd
   http://www.springframework.org/schema/mvc
   http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
   <context:component-scan base-package = "com.tutorialspoint" />
   <mvc:annotation-driven />
</beans>

在这里,我们创建了一个 XML 映射的 POJO User,并在 UserController 中,我们返回了 User。Spring 会根据 RequestMapping 自动处理 XML 转换。

Here, we have created an XML Mapped POJO User and in the UserController, we have returned the User. Spring automatically handles the XML conversion based on RequestMapping.

创建源文件和配置文件后,导出应用程序。右键单击应用程序,使用 Export → WAR File 选项,将你的 TestWeb.war 文件保存到 Tomcat 的 webapps 文件夹中。

Once you are done with creating source and configuration files, export your application. Right click on your application, use Export → WAR File option and save your TestWeb.war file in Tomcat’s webapps folder.

现在,启动 Tomcat 服务器,确保可以使用标准浏览器访问 webapps 文件夹中的其他网页。尝试一个 URL - http://localhost:8080/TestWeb/mahesh ,我们将看到以下屏幕。

Now, start the Tomcat server and make sure you are able to access other webpages from the webapps folder using a standard browser. Try a URL – http://localhost:8080/TestWeb/mahesh and we will see the following screen.
