1、利用反射将Java Bean中string类型属性值为null的设为""
1 SomeClass obj = new SomeClass(); 2 Class c = SomeClass.class; 3 Field[] fields = c.getDeclaredFields(); 4 for(int i = 0; i < fields.length; i++) 5 { 6 String fieldName = fields[i].getName(); 7 fieldName = fieldName.substring(0, 1).toUpperCase() + fieldName.substring(1); 8 9 try 10 { 11 Method getM = c.getMethod("get" + fieldName); 12 String strVal = (String) getM.invoke(obj); 13 if(strVal == null) 14 { 15 Method setM = c.getMethod("set" + fieldName, String.class); 16 setM.invoke(obj, ""); 17 } 18 } 19 catch (Exception ex) 20 { 21 LOGGER.error("Java Reflect Error " + ex.toString()); 22 } 23 }
