我正在尝试构建一个简单的Restful api,它返回用户的详细信息。
我已提到this链接。
以下是我的课程:
API服务类:
package com.demoapp;
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;
import org.omg.Messaging.SyncScopeHelper;
@Path("/AddUserApi")
public class AddUserApi {
@GET
@Path("/users")
@Produces(MediaType.APPLICATION_XML)
public List<User> getUsers(){
return UserUtil.getUserList();
}
}
Dao Class:
package com.demoapp;
import java.io.Serializable;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "user")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
String name="";
String u_name="";
String password="";
String email="";
String user_type="";
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getU_name() {
return u_name;
}
public void setU_name(String u_name) {
this.u_name = u_name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getUser_type() {
return user_type;
}
public void setUser_type(String user_type) {
this.user_type = user_type;
}
}
实用工具类:
package com.demoapp;
import java.util.List;
public class UserUtil {
public static String mysql_ip="jdbc:mysql://10.119.32.86/";
public static String metadata_database="haas";
public static String mysql_username="root";
public static String mysql_password="";
public static List<User> getUserList(){
List<User> users=new ArrayList<User>();
User user=new User();
user.setName("abc");
user.setU_name("ab_c");
user.setPassword("1234");
user.setUser_type("normal");
user.setEmail("abc@gmail.com");
users.add(user);
return users;
}
}
的web.xml

我从网站上下载了泽西jar并提取了3个文件夹,并在构建路径中添加了这些jar。
我根据教程做了一切。 仍显示此错误:
答案 0 :(得分:2)
如果服务器已启动并正在运行,并且应用程序的部署没有错误,则应在以下URL中提供您的端点:
http://[host]:[port]/[context]/rest/AddUserApi/users
其中:
[context]
是您的WAR文件的名称(没有.war
扩展名)。/rest
来自web.xml
:<url-pattern>/rest/*</url-pattern>
。/AddUserApi
来自@Path
课程的AddUserApi
注释。/users
来自@Path
方法的getUsers()
注释。答案 1 :(得分:0)
您的网址应为:localhost:8082 / UserAPI / rest / AddUserApi / users
