spring可以对不同Class类型进行相应的转换。比如String转成Boolean. Boolean转成string类.以下是个简单的例子
@Test
public void testConverter() {
DefaultConversionService serivce = new DefaultConversionService();
boolean actual = serivce.canConvert(String.class, Boolean.class);
Assert.assertEquals(true, actual);
Object acc = serivce.convert("true", Boolean.class);
Assert.assertEquals(true, ((Boolean)acc).booleanValue());
}
