# 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。

# 2.配置 #

## 1.pom.xml配置如下： ##

                <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;
    @XmlRootElement
    public 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][SouthEast]

后台接收到的数据如下：  
![这里写图片描述][SouthEast 1]

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][Jersey_Jersey_JSON]这篇文章，这里不在赘述。
