我实际上是 REST WS 的新手，但我真的不明白415 Unsupported Media Type。
我正在 Firefox 上使用 Poster 测试我的 REST，并且GET对我来说工作正常，POST（当它是 aapplication/xml时）但是当我尝试application/json它根本没有到达 WS 时，服务器拒绝它。
这是我的网址：http://localhost:8081/RestDemo/services/customers/add
这是JSON我要发送的：{"name": "test1", "address" :"test2"}
这是XML我要发送的：
<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;
}
}
