spring + jersey MediaType.APPLICATION_XML错误

标签： hibernate spring-mvc jersey

我正在尝试使用Sprig + jersey编写Web服务，这是我的代码：

package orgProfiles.webserviceJersey;

import java.util.List;

import javax.ws.rs.GET;
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 orgProfiles.model.Registration;
import orgProfiles.repository.RegisterUserRepository;

@Path("mytest")
@Component
public class TestService {
    @Autowired
    private RegisterUserRepository registerUserRepository;

    @GET
    @Produces(MediaType.APPLICATION_XML)
    public List<Registration> hitest() {
        return registerUserRepository.findAll();
    }

}

存储库：

package orgProfiles.repository;

import java.util.List;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;

import orgProfiles.model.Registration;
@Repository("registerUserRepository")
public interface RegisterUserRepository extends JpaRepository<Registration,Long>{
    @Query("Select c from Registration c where c.name=:companyname")
    Registration findByCompanyname(@Param("companyname")String companyname);

//    @Query("Select c from Registration c where c.place like %:place%")
    List<Registration> findByPlaceContaining(String place);

//    @Query("Select c from Registration c where c.name like %:name%")
    List<Registration> findByNameContaining( String name);

//  @Query("Select c from Registration c where c.type like :type")
    List<Registration> findByTypeContaining(String type);

    List<Registration> findByTypeAndPlace(String type, String place);

    List<Registration> findByNameAndPlace(String name, String place);
}

型号：

package orgProfiles.model;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
public class Registration {

    @GeneratedValue
    private Long id;
    private String name;
    @Column(name="description", columnDefinition="TEXT")
    private String description;
    private String type;
    private String place;
    @Column(name="address", columnDefinition="TEXT")
    private String address;

    private String website;
    private double latitude;
    private Long phoneNum;
    private double longitude;

    @OneToOne(cascade=CascadeType.ALL,fetch = FetchType.EAGER)
    @JoinColumn(name="id")  
    private LoginCredentials loginCredentials;
    public String getAddress() {
        return address;
    }
    public String getDescription() {
        return description;
    }
    public Long getId() {
        return id;
    }

    public double getLatitude() {
        return latitude;
    }
    public LoginCredentials getLoginCredentials() {
        return loginCredentials;
    }
    public double getLongitude() {
        return longitude;
    }
    public String getName() {
        return name;
    }
    public Long getPhoneNum() {
        return phoneNum;
    }
    public String getPlace() {
        return place;
    }
    public String getType() {
        return type;
    }

    public String getWebsite() {
        return website;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public void setDescription(String description) {
        this.description = description;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public void setLatitude(double latitude) {
        this.latitude = latitude;
    }

    public void setLoginCredentials(LoginCredentials loginCredentials) {
        this.loginCredentials = loginCredentials;
    }
    public void setLongitude(double longitude) {
        this.longitude = longitude;
    }

    public void setName(String name) {
        this.name = name;
    }
    public void setPhoneNum(Long phoneNum) {
        this.phoneNum = phoneNum;
    }
    public void setPlace(String place) {
        this.place = place;
    }

    public void setType(String type) {
        this.type = type;
    }
    public void setWebsite(String website) {
        this.website = website;
    }

当我尝试访问该服务时（http：// l o c alhost：8080 / orgProfiles / ws / mytest），它最终会出现HTTP状态500 - 内部服务器错误错误。我如何将我的实体标记为@XmlRootElement？当我把那个注释说它XmlRootElement无法解析为一个类型。当我将mediatype更改为MediaType.APPLICATION_JSON时，它的工作正常。我可以添加JAXB依赖项来获取@XMlRootElement注释吗？先谢谢

尝试添加jersey-json依赖项：

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>${jersey.version}</version>
    </dependency>
