通过反射把一个类的值传给另外一个类

public static <T> T assign(Object source, Class<T> clazz) {
try {
T target = clazz.newInstance();
Class sourceClass = source.getClass();
Field[] fields = sourceClass.getDeclaredFields();
for (Field field : fields) {
field.setAccessible(true);
Object value = field.get(source);
if (value != null){
Class fType = field.getType();
Field field1;
try {
//如果source的参数不在目标类中，会报错并跳过。
                        field1 = clazz.getDeclaredField(field.getName());
} catch (NoSuchFieldException ne){
continue;
}
Class cType = field1.getType();
field1.setAccessible(true);
if (!fType.equals(cType)){
//如果目标类是字符串的话其余的类可以转成字符串
                        if (cType.equals(String.class)){
                            field1.set(target,value.toString());
}
} else {
field1.set(target,value);
}
}
}
return target;
} catch (Exception e){
e.printStackTrace();
}
return null;
}
