我实际上是 REST WS 的新手,但我真的不明白这个 415 Unsupported Media Type
。
我正在 Firefox 上使用 Poster 测试我的 REST,并且 GET
对我来说很好,而且 POST
(当它是 application/xml
application/json
) ---
它根本没有到达WS,服务器拒绝它。
这是我的网址:http://localhost:8081/RestDemo/services/customers/add
这是 JSON
我正在发送: {"name": "test1", "address" :"test2"}
这是 XML
我正在发送:
<customer>
<name>test1</name>
<address>test2</address>
</customer>
这是我的资源类:
@Produces("application/xml")
@Path("customers")
@Singleton
@XmlRootElement(name = "customers")
public class CustomerResource {
private TreeMap<Integer, Customer> customerMap = new TreeMap<Integer, Customer>();
public CustomerResource() {
// hardcode a single customer into the database for demonstration
// purposes
Customer customer = new Customer();
customer.setName("Harold Abernathy");
customer.setAddress("Sheffield, UK");
addCustomer(customer);
}
@GET
@XmlElement(name = "customer")
public List<Customer> getCustomers() {
List<Customer> customers = new ArrayList<Customer>();
customers.addAll(customerMap.values());
return customers;
}
@GET
@Path("/{id}")
@Produces("application/json")
public String getCustomer(@PathParam("id") int cId) {
Customer customer = customerMap.get(cId);
return "{\"name\": \" " + customer.getName() + " \", \"address\": \"" + customer.getAddress() + "\"}";
}
@POST
@Path("/add")
@Produces(MediaType.APPLICATION_JSON)
@Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public String addCustomer(Customer customer) {
//insert
int id = customerMap.size();
customer.setId(id);
customerMap.put(id, customer);
//get inserted
Customer result = customerMap.get(id);
return "{\"id\": \" " + result.getId() + " \", \"name\": \" " + result.getName() + " \", \"address\": \"" + result.getAddress() + "\"}";
}
}
编辑1:
这是我的客户类:
@XmlRootElement
public class Customer implements Serializable {
private int id;
private String name;
private String address;
public Customer() {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}

问题在于 bean Customer 的反序列化。您的程序知道如何在 XML 中使用 Daniel 编写的 JAXB,但很可能不知道如何在 JSON 中进行。
这里有一个 Resteasy/Jackson 的例子 http://www.mkyong.com/webservices/jax-rs/integrate-jackson-with-resteasy/
