Example

customize a POJO json output

    @GetMapping("/user")
    //use annotation to customize your json output *_*
    //clazz -- the POJO class that you want to customize
    //includes -- the properties in POJO that you want to save
    @SerializeField(clazz = User.class,includes = {"name","id"})
    public User user() {
        User user = new User(1L, "liuyis", "123456");
        return user;
    }

you will get response like that : {"id":1,"name":"liuyis"}

customize two POJO json output

    @GetMapping("/user2")
    //use annotation to customize your json output *_*
    //clazz -- the POJO class that you want to customize
    //includes -- the properties in POJO that you want to save
    @SerializeField(clazz = User.class,includes = {"name", "id", "addresses"})
    //use @MultiSerializeField annotation to customize the second POJO json output *_*
    //clazz -- the POJO class that you want to customize
    //excludes -- the properties in POJO that you do not want to show in json output
    @MultiSerializeField(clazz = Address.class, excludes = {"user"})
    public User user2() {
        User user = new User(1L, "liuyis", "123456");
        List<Address> addresses = new ArrayList<>();
        Address a1 = new Address("liuyis's home", "liuyis's school", user);
        Address a2 = new Address("liuyis's home2", "liuyis's school2", user);
        addresses.add(a1);
        addresses.add(a2);
        user.setAddresses(addresses);

        return user;
    }

you will get response like that: {"addresses":[{"home":"liuyis's home","school":"liuyis's school"},{"home":"liuyis's home2","school":"liuyis's school2"}],"id":1,"name":"liuyis"}

    @GetMapping("/address")
    //use annotation to customize your json output *_*
    //clazz -- the POJO class that you want to customize
    //includes -- the properties in POJO that you wan to save
    @SerializeField(clazz = Address.class, includes = {"school", "home", "user"})
    //use @MultiSerializeField annotation to customize the second POJO json output *_*
    //clazz -- the POJO class that you want to customize
    //excludes -- the properties in POJO that you do not want to show in json output
    @MultiSerializeField(clazz = User.class, excludes = {"addresses"})
    public Address address(){
        User user = new User(1L, "liuyis", "123456");
        List<Address> addresses = new ArrayList<>();
        Address a1 = new Address("liuyis's home", "liuyis's school", user);
        Address a2 = new Address("liuyis's home2", "liuyis's school2", user);
        addresses.add(a1);
        addresses.add(a2);
        user.setAddresses(addresses);

        return a1;
    }

you will get response like that:{"home":"liuyis's home","school":"liuyis's school","user":{"id":1,"name":"liuyis"}}

customize mutiple POJO json output
