json-lib首字母大写的json串转javabean

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

测试程序：

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、主函数

JsonConfig config=new JsonConfig();config.setRootClass(Person.class);

Map<String,Class<?>> classMap = new HashMap<String,Class<?>>();classMap.put("addresses", Address.class);config.setClassMap(classMap);

PropertyNameProcessor lowerCasePropertyNameProcessor = new PropertyNameProcessor() {    @Override    public String processPropertyName(Class aClass, String s) {        return s.substring(0,1).toLowerCase() + s.substring(1);    }};

config.registerJavaPropertyNameProcessor(Person.class, lowerCasePropertyNameProcessor);config.registerJavaPropertyNameProcessor(Address.class, lowerCasePropertyNameProcessor);

//大写转bean小写String jsonString = "{\"Id\":3,\"Name\":\"xiaoming\",\"Addresses\":[{\"Name\":\"xian\"}]}";JSONObject jsonObject = JSONObject.fromObject(jsonString);Person person = (Person) JSONObject.toBean(jsonObject, config);System.out.println(person);

4、运行结果Person{id=3, name=‘xiaoming‘, addresses=[Address{name=‘xian‘}]}
