总结

1.前言

对于数据量较大的提交，我们一般习惯于用javabean把数据封装起来一起提交，在服务端使用json数据格式接收，映射到jababean上。这里简单写几个例子。

以Spring集成Jersey开发，实现rest约束例子的例子源码没基础开发，下载地址提取码：2itw

2.配置

1.pom.xml配置如下：

其中重点是：

<!--POJO对象被序列化成 JSON 对象 -->        <dependency>            <groupId>org.glassfish.jersey.media</groupId>            <artifactId>jersey-media-json-jackson</artifactId>            <version>2.26</version>            <exclusions>                <exclusion>                    <groupId>javax.ws.rs</groupId>                    <artifactId>javax.ws.rs-api</artifactId>                </exclusion>            </exclusions>        </dependency>        <dependency>            <groupId>org.glassfish.jersey.media</groupId>            <artifactId>jersey-media-json-jettison</artifactId>            <version>2.26</version>        </dependency>        <dependency>            <groupId>com.sun.jersey</groupId>            <artifactId>jersey-json</artifactId>            <version>1.18</version>        </dependency>

这几个jar的依赖

2.创建个TestRo.java用于传递结构体:

import javax.xml.bind.annotation.XmlRootElement;@XmlRootElementpublic class TestRo {    private String id;    private String name;    private String age;    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getAge() {        return age;    }    public void setAge(String age) {        this.age = age;    }}

重点关注

@XmlRootElement

用该注解标识javabean,代码里变量名和传递的参数名保持一致。

3.编写Jersey的资源，创建api接口

import javax.ws.rs.Consumes;import javax.ws.rs.GET;import javax.ws.rs.POST;import javax.ws.rs.Path;import javax.ws.rs.Produces;import javax.ws.rs.core.MediaType;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import com.jax.JerseySpring.bean.TestRo;import com.jax.JerseySpring.mgr.acct.IAcctMgr;@Component@Path("/demo")public class HelloResources {    @Autowired    public IAcctMgr acctMgr;    @GET    @Path("/hello")    public String acct() {        String result = "failure";        try {            result = acctMgr.getAcctByCd("9527");            System.out.println("结果：" + result);        } catch (Exception e) {            System.out.println(e);        }        return result;    }    /**     * 测试传输javabean     */    @POST    @Produces(MediaType.APPLICATION_JSON)    @Consumes(MediaType.APPLICATION_JSON)     @Path("/")    public String addOrder1(TestRo testRo) {        try {            return "post方式，新建成功:";        } catch (Throwable e) {            System.out.println(e);        }        return "post方式，新建失败";    }}

这里同时也测试了使用某个资源的根路径创建URI的例子，对比：
api/demo/
和
api/demo/hello

3.测试

提交的数据如下图：
这里写图片描述

后台接收到的数据如下：
这里写图片描述

说明后台成功的接收到的javabean数据。

4.总结

以上是使用JAXB的方式传递javabean，其中已经够大部分情况下使用，只要是基本HTTP方式传输的，当然还有一种基本POJO方式。大家可参考Jersey框架二：Jersey对JSON的支持这篇文章，这里不在赘述。
