通过反射获取Hibernate实体字段名

shewolfep

Hibernate实体形如：/** 用户名 */private String userName;/** 密码 */private String password;/** 用户类型 */private String typeId;/** 用户状态 */private String status;@Column(name = "USER_NAME", nullable = false, length = 36)public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}@Column(name = "PASSWORD", nullable = false, length = 32)public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}@Column(name = "TYPE_ID", nullable = false, length = 10)public String getTypeId() {return typeId;}public void setTypeId(String typeId) {this.typeId = typeId;}@Column(name = "STATUS", nullable = false, length = 10)public String getStatus() {return status;}获取所有字段的方法
/** * <pre> * 获取实体所有字段 * @param clazz 实体类型 * @param strs 需要排除的字段 * @return Map<String, Method> 其中key为数据库字段名称，value为字段对应的get方法 * 2011-4-23 下午01:52:06 * </pre> */public static Map<String, Method> getFields(Class<?> clazz, List<String> strs) {Map<String, Method> map = new HashMap<String, Method>();Method[] methods = clazz.getMethods();for (Method method : methods) {Column c = method.getAnnotation(Column.class);if (null!=strs&&strs.contains(c.name())) {continue;}if (null != c) {map.put(c.name(), method);} else {JoinColumn jc = method.getAnnotation(JoinColumn.class);if (null!=strs&&strs.contains(jc.name())) {continue;}if (null != jc) {map.put(jc.name(), method);}}}return map;}
