HAP_使用CXF开发REST_简单demo

本文详细介绍如何使用CXF框架实现RESTful风格的服务接口。包括导入必要的依赖库、定义DTO对象、创建接口及其实现类，并配置Spring上下文来启动REST服务。

步骤一：导包

 <!-- 自己导入的包-->
        <!-- CXF -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxrs</artifactId>
            <version>3.1.4</version>
        </dependency>

        <!-- Jackson -->
        <dependency>
            <groupId>com.fasterxml.jackson.jaxrs</groupId>
            <artifactId>jackson-jaxrs-json-provider</artifactId>
            <version>2.9.5</version>
            <!-- <version>2.4.1</version>-->
        </dependency>

        <dependency>
            <groupId>com.sun.jersey.samples</groupId>
            <artifactId>jacksonjsonprovider</artifactId>
            <version>1.18.1</version>
        </dependency>


        <!-- https://mvnrepository.com/artifact/javax.ws.rs/javax.ws.rs-api -->
        <dependency>
            <groupId>javax.ws.rs</groupId>
            <artifactId>javax.ws.rs-api</artifactId>
            <version>2.0.1</version>
        </dependency>

步骤二：新建一个简单的dto

package wht.ora20796.dto;

import java.io.Serializable;

public class Ora20796CXF implements Serializable {
    private String name;
    private String passwd;

    public Ora20796CXF() {
    }

    public Ora20796CXF(String name, String passwd) {
        this.name = name;
        this.passwd = passwd;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPasswd() {
        return passwd;
    }

    public void setPasswd(String passwd) {
        this.passwd = passwd;
    }
}

步骤三：编写接口类

package wht.ora20796.service;

import com.hand.hap.system.dto.ResponseData;
import wht.ora20796.dto.Ora20796CXF;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

import java.util.List;

import static javax.ws.rs.core.MediaType.APPLICATION_JSON;

public interface IOra20796CXF {
    @GET
    @Path("/user")
    @Produces(APPLICATION_JSON)
    ResponseData retrieveAllUsers();
}

步骤四：接口实现类

package wht.ora20796.service.impl;

import com.hand.hap.system.dto.ResponseData;
import wht.ora20796.dto.Ora20796CXF;
import wht.ora20796.service.IOra20796CXF;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import java.util.ArrayList;
import java.util.List;

import static javax.ws.rs.core.MediaType.APPLICATION_JSON;

public class Ora20796CXFImpl implements IOra20796CXF {
//https://blog.youkuaiyun.com/victor_cindy1/article/details/72868424
    @GET
    @Path("/user")
    @Produces(APPLICATION_JSON)
    @Override
    public ResponseData retrieveAllUsers() {
        ResponseData responseData=new ResponseData();
        List<Ora20796CXF> list=new ArrayList<>();
        Ora20796CXF ora20796CXF1=new Ora20796CXF("csz","123");
        Ora20796CXF ora20796CXF2=new Ora20796CXF("test","testpd");
        list.add(ora20796CXF1);
        list.add(ora20796CXF2);
        responseData.setMessage("成功");
        responseData.setRows(list);
        return responseData;
    }
}

更改配置文件
