javabean实体类对象转为Map类型对象的方法

在项目中需要用到对象转Map的需求，就记录下来。防止以后需要用到的。

 public static Map<String, Object> beanToMap(Object obj) {          Map<String, Object> params = new HashMap<String, Object>(0);          try {              PropertyUtilsBean propertyUtilsBean = new PropertyUtilsBean();              PropertyDescriptor[] descriptors = propertyUtilsBean.getPropertyDescriptors(obj);              for (int i = 0; i < descriptors.length; i++) {                  String name = descriptors[i].getName();                  if (!"class".equals(name)) {                      params.put(name, propertyUtilsBean.getNestedProperty(obj, name));                  }              }          } catch (Exception e) {              e.printStackTrace();          }          return params;  }

需要的jar包 maven项目上

<dependency><groupId>commons-logging</groupId><artifactId>commons-logging</artifactId><version>1.1.3</version></dependency><dependency><groupId>commons-beanutils</groupId><artifactId>commons-beanutils</artifactId><version>1.9.2</version></dependency>

获取上面两个jar的网址分别是：http://commons.apache.org/beanutils/
