我在下面以及与邮递员一起测试时有一些代码。发生错误“ 500”。我不了解“ @Produces(MediaType.APPLICATION_XML)”的优点。是否自动将返回类型定义为XML。
import java.sql.SQLException;
import java.util.List;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("/UserService")
public class UserService {
UserDAO userDAO = new UserDAO();
@GET
@Path("/users")
@Produces(MediaType.APPLICATION_XML)
public List<User> getUsers() throws ClassNotFoundException, SQLException {
return userDAO.getAllUsers();
}
}
最佳答案
//To process HTTP GET requests.
@GET
//@Path Identifies the URI path that a resource class will serve requests for.
@Path("/abcd")
//@Produces defines the media type(s) that the methods of a resource class can produce.
@Produces(MediaType.APPLICATION_XML
我希望您已经准备了User类-具有XmlRootElement和XML元素
举个例子-
@XmlRootElement(name="User")
public class User{
private int id;
private String name;
public User() {
}
@XmlElement
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@XmlElement
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
关于java - 静态返回类型xml或json,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/53409911/
