1.添加依赖

<dependency><groupId>commons-beanutils</groupId><artifactId>commons-beanutils</artifactId><version>1.9.2</version></dependency>

2.JavaBean转化为Map

        PersonBean person = new PersonBean();        person.setAge(12);        person.setGender("mail");        person.setName("Tom");        Map<String, Object> map = PropertyUtils.describe(person);        for (Map.Entry<String, Object> entry : map.entrySet()) {        System.out.println(entry.getKey() + ": " + entry.getValue());        }

结果为：

age: 12name: Tomclass: class com.mycompany.app.PersonBeangender: mail

2.Map转化为JavaBean

        PersonBean person = new PersonBean();        Map<String, Object> map = new HashMap<String, Object>();        map.put("name", "Mike");        map.put("age", new Integer(25));map.put("gender", "male");        BeanUtils.populate(person, map);                System.out.println("name: " + person.getName());        System.out.println("age: " + person.getAge());        System.out.println("gender: " + person.getGender());

结果为：

name: Mikeage: 25gender: male
