json-lib过滤属性

依赖jar：

commons-beanutils-1.9.3.jar?

commons-collections-3.1.jar

commons-lang-2.4.jar

commons-logging-1.2.jar

ezmorph-1.0.6.jar

json-lib-2.4-jdk15.jar

直接上程序

1、Person.java:

import java.util.List;

/** * Created by Administrator on 2017/5/6. */public class Person {    private int id;    private String name;    private List<Address> addresses;

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 List<Address> getAddresses() {        return addresses;    }

public void setAddresses(List<Address> addresses) {        this.addresses = addresses;    }

@Override    public String toString() {        return "Person{" +                "id=" + id +                ", name=‘" + name + ‘\‘‘ +                ", addresses=" + addresses +                ‘}‘;    }}

2、Address.java:

public class Address {    private String name;

public String getName() {        return name;    }

public void setName(String name) {        this.name = name;    }

@Override    public String toString() {        return "Address{" +                "name=‘" + name + ‘\‘‘ +                ‘}‘;    }}

3、测试程序

Person person = new Person();person.setId(1);person.setName("xiaoming");List<Address> addresses = new ArrayList<Address>();Address address = new Address();address.setName("xian");addresses.add(address);person.setAddresses(addresses);

//设置过滤字段  方法1 使用setJsonPropertyFilter

JsonConfig jsonConfig = new JsonConfig();PropertyFilter filter = new PropertyFilter() {    //参数1：person对象  如果有两个fieldName都是name，则都会被过滤，无法精确控制    public boolean apply(Object object, String fieldName, Object fieldValue) {        return fieldName.equals("name");    }};jsonConfig.setJsonPropertyFilter(filter);System.out.println(JSONObject.fromObject(person, jsonConfig).toString());

//方法2  过滤id

jsonConfig.setExcludes(new String[]{"id"}); //java

说明：这两这种方法，如果出现多个相同属性，设置了过滤后，会全部过滤掉，无法精确控制具体哪一个属性。
