使用接口来声明多个视图

package org.byron4j.springMVC4_rest_jackson_jsonview_annotation;
     
    public class Profile {
        public interface PublicView {}
        public interface FriendsView extends PublicView{}
        public interface FamilyView extends FriendsView {}
    }

在值对象的get方法上指定视图

import org.byron4j.springMVC4_rest_jackson_jsonview_annotation.Profile;
     
    import com.fasterxml.jackson.annotation.JsonView;
     
    public class User {
        @JsonView(Profile.PublicView.class)     
        private String userId;
        private String password;    
        private int age;            
        @JsonView(Profile.FamilyView.class) 
        private long mobnum;        
        @JsonView(Profile.FriendsView.class)
        private String mailId;
        @JsonView(Profile.PublicView.class) 
        private String name;    
        @JsonView(Profile.PublicView.class)     
        private College college;
        @JsonView(Profile.PublicView.class)     
        private Address address;
        public User(String userId, String password, int age, long mobnum, String mailId, 
                String name, College college, Address address) {
            this.userId = userId;
            this.password = password;
            this.age = age;
            this.mobnum = mobnum;
            this.mailId = mailId;
            this.name = name;
            this.college = college;
            this.address = address;
        }
        public String getUserId() {
            return userId;
        }
        public void setUserId(String userId) {
            this.userId = userId;
        }
        public String getPassword() {
            return password;
        }
        public void setPassword(String password) {
            this.password = password;
        }
        public int getAge() {
            return age;
        }
        public void setAge(int age) {
            this.age = age;
        }
        public long getMobnum() {
            return mobnum;
        }
        public void setMobnum(long mobnum) {
            this.mobnum = mobnum;
        }
        public String getMailId() {
            return mailId;
        }
        public void setMailId(String mailId) {
            this.mailId = mailId;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public College getCollege() {
            return college;
        }
        public void setCollege(College college) {
            this.college = college;
        }
        public Address getAddress() {
            return address;
        }
        public void setAddress(Address address) {
            this.address = address;
        }
    }

在controller方法上指定视图

import java.util.List;
     
    import org.byron4j.springMVC4_rest_jackson_jsonview_annotation.pojo.Name;
    import org.byron4j.springMVC4_rest_jackson_jsonview_annotation.pojo.User;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.MediaType;
    import org.springframework.http.ResponseEntity;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RestController;
     
    import com.fasterxml.jackson.annotation.JsonView;
    @RestController
    @RequestMapping("/app")
    public class UserController {
        @Autowired
        private UserService userService;
        @JsonView(Profile.PublicView.class)
        @RequestMapping(value= "/publicprofile", produces = MediaType.APPLICATION_JSON_VALUE)
        public List<user> getAllPublicProfile() {
            List<user> users = userService.getAllUsers();
            return users;
        }   
        @JsonView(Profile.FriendsView.class)
        @RequestMapping(value= "/friendsprofile", produces = MediaType.APPLICATION_JSON_VALUE)
        public List<user> getAllFriendsProfile() {
            List<user> users = userService.getAllUsers();
            return users;
        }   
        @JsonView(Profile.FamilyView.class)
        @RequestMapping(value= "/familyprofile", produces = MediaType.APPLICATION_JSON_VALUE)
        public List<user> getAllFamilyProfile() {
            List<user> users = userService.getAllUsers();
            return users;
        }       
        @RequestMapping(value= "/completeprofile/{userId}", produces = MediaType.APPLICATION_JSON_VALUE)
        public User getCompleteProfileById(@PathVariable(value = "userId") String userId) {
            User user = userService.getUserById(userId);
            return user;
        }
        @RequestMapping(value="/save", method = RequestMethod.POST)
        public ResponseEntity<string> save(@RequestBody Name name) {
            StringBuffer output = new StringBuffer();
            if (name.getFirstName() != null) {
                output.append(" ").append(name.getFirstName());
            }
            if (name.getMiddleName() != null) {
                output.append(" ").append(name.getMiddleName());
            }
            if (name.getLastName() != null) {
                output.append(" ").append(name.getLastName());
            }       
            return new ResponseEntity<string>(output.toString(), HttpStatus.CREATED);
        }
