我是Spring框架的新手，我试图在春天休息时做一个Web服务，然后我就会有以下控制器返回Customer对象列表。
@RestController
@RequestMapping(RestURIConstants.SERVICES_ROUTE + "customer")
public class CustomerService
{
@RequestMapping(value="/getCustomers",method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<List<Customer>> getCustomers()
{
System.out.println("calling get customers service");
JpaGenericController<Customer> customerDao = new JpaGenericController<Customer>( Customer.class );
List<Customer> customers = customerDao.findAll();
return new ResponseEntity<List<Customer>>(customers,HttpStatus.OK);
}
}
我的班级客户如下：
@Entity
@Table(name = "Customer")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "Customer.findAll", query = "SELECT c FROM Customer c"),
@NamedQuery(name = "Customer.findByCode", query = "SELECT c FROM Customer c WHERE c.code = :code"),
@NamedQuery(name = "Customer.findByName", query = "SELECT c FROM Customer c WHERE c.name = :name"),
@NamedQuery(name = "Customer.findByAddress", query = "SELECT c FROM Customer c WHERE c.address = :address"),
@NamedQuery(name = "Customer.findByPhoneOne", query = "SELECT c FROM Customer c WHERE c.phoneOne = :phoneOne"),
@NamedQuery(name = "Customer.findByPhoneTwo", query = "SELECT c FROM Customer c WHERE c.phoneTwo = :phoneTwo"),
@NamedQuery(name = "Customer.findByCreditLimit", query = "SELECT c FROM Customer c WHERE c.creditLimit = :creditLimit"),
@NamedQuery(name = "Customer.findByCurrentCredit", query = "SELECT c FROM Customer c WHERE c.currentCredit = :currentCredit")})
public class Customer implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 255)
@Column(name = "code")
private String code;
@Size(max = 255)
@Column(name = "name")
private String name;
@Size(max = 45)
@Column(name = "address")
private String address;
@Size(max = 45)
@Column(name = "phoneOne")
private String phoneOne;
@Size(max = 45)
@Column(name = "phoneTwo")
private String phoneTwo;
@Column(name = "creditLimit")
private Short creditLimit;
@Column(name = "currentCredit")
private Short currentCredit;
public Customer() {
}
public Customer(String code) {
this.code = code;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
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;
}
public String getPhoneOne() {
return phoneOne;
}
public void setPhoneOne(String phoneOne) {
this.phoneOne = phoneOne;
}
public String getPhoneTwo() {
return phoneTwo;
}
public void setPhoneTwo(String phoneTwo) {
this.phoneTwo = phoneTwo;
}
public Short getCreditLimit() {
return creditLimit;
}
public void setCreditLimit(Short creditLimit) {
this.creditLimit = creditLimit;
}
public Short getCurrentCredit() {
return currentCredit;
}
public void setCurrentCredit(Short currentCredit) {
this.currentCredit = currentCredit;
}
@Override
public int hashCode() {
int hash = 0;
hash += (code != null ? code.hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Customer)) {
return false;
}
Customer other = (Customer) object;
if ((this.code == null && other.code != null) || (this.code != null && !this.code.equals(other.code))) {
return false;
}
return true;
}
@Override
public String toString() {
return "com.dev.model.Customer[ code=" + code + " ]";
}
}
我使用了杰克逊映射器
<!-- JACKSON Mapper-->
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
但是当我尝试访问Web服务时，我得到以下错误：
HTTP Status 406 -
type Status report
message
description The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.
那么，我做错了什么？
我需要在applicationContext中设置一些内容吗？
应用上下文

更新
我尝试放置生成服务的文件类型，但不起作用
@RequestMapping(
value="/getCustomers",
method = RequestMethod.GET,
produces={"application/json"}
)
@ResponseBody
public ResponseEntity<List<Customer>> getCustomers()
{
System.out.println("calling get customers service");
JpaGenericController<Customer> customerDao = new JpaGenericController<Customer>( Customer.class );
List<Customer> customers = customerDao.findAll();
return new ResponseEntity<List<Customer>>(customers,HttpStatus.OK);
}
由firefox生成的标题：
http://localhost:9080/controller/services/test/getCustomers

您需要将 添加到spring xml中以使spring解析合理的默认值
