jAVA中如何做到contain 不区分大小写呢?

直接上代码:

/***
	 * 是否包含指定字符串,不区分大小写
	 * @param input : 原字符串
	 * @param regex
	 * @param replacement
	 * @return
	 */
	public static boolean contain2(String input, String regex) {
		if(ValueWidget.isNullOrEmpty(input)){
			return false;
		}
		Pattern p = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
		Matcher m = p.matcher(input);
		boolean result = m.find();
		return result;
	}

 测试:

@Test
	public void test_contain(){
		String source="aava is my best";
		org.junit.Assert.assertFalse(RegexUtil.contain2(source, "Java"));
		org.junit.Assert.assertFalse(RegexUtil.contain2(source, "java"));
		org.junit.Assert.assertFalse(RegexUtil.contain2("jaava is my best", "java"));
		org.junit.Assert.assertTrue(RegexUtil.contain2("ajava is my best", "java"));
		org.junit.Assert.assertTrue(RegexUtil.contain2("aJava is my best", "java"));
	}
