Spring 4 REST 程序使用 JAXB 返回 XML 中的列表

使用Spring 4 REST程序可以轻松地将数据以XML格式返回给客户端。其中一种常见的场景是返回包含列表的XML数据。在本文中，我们将介绍如何使用JAXB（Java Architecture for XML Binding）来实现这一目标。

java
public class Blog {
    private List posts;
    public List getPosts() {
        return posts;
    }
    public void setPosts(List posts) {
        this.posts = posts;
    }
}
public class Post {
    private String title;
    private String content;
    // getters and setters
}

                    com.example.Blog
                
            
        
    

java
@RestController
public class BlogController {
    @RequestMapping(value = "/blog", method = RequestMethod.GET, produces = "application/xml")
    public Blog getBlog() {
        List posts = new ArrayList<>();
        
        Post post1 = new Post();
        post1.setTitle("Spring 4 REST");
        post1.setContent("Using JAXB to return XML list");
        posts.add(post1);
        
        Post post2 = new Post();
        post2.setTitle("Spring Boot");
        post2.setContent("Building RESTful APIs");
        posts.add(post2);
        
        Blog blog = new Blog();
        blog.setPosts(posts);
        
        return blog;
    }
}
