spring2.5+JDK1.8报错的解决办法

annotation-config are only available on JDK 1.5 and higher

今天遇到一个工程，启动时报这个错！可明明我的JDK是1.8呀。
原来这个工程的spring是2.5，网上说spring2.5必须要求JDK1.5以上版本，但不能兼容1.8。

没道理会这样吧？

原来spring-2.5.5.jar有一个检查JDK版本号的类，编码质量略低，导致1.8被误认为未达到“JDK1.5以上版本”这个要求。。。
org.springframework.core.JdkVersion
于是找到一个spring-core-3.x.RELEASE.jar，用其中的JdkVersion这个类替换spring-2.5.5.jar对应class，问题解决！

注意：别用spring-core-4.x.RELEASE.jar，JdkVersion.isAtLeastJava15()方法已经没有了！

// spring-2.5.5.jarstatic {    if (javaVersion.indexOf("1.7.") != -1) {        majorJavaVersion = 4;    } else if (javaVersion.indexOf("1.6.") != -1) {        majorJavaVersion = 3;    } else if (javaVersion.indexOf("1.5.") != -1) {        majorJavaVersion = 2;    } else {        majorJavaVersion = 1;    }}// spring-core-3.2.9.RELEASE.jarstatic {    if (javaVersion.contains("1.8.")) {        majorJavaVersion = 5;    } else if (javaVersion.contains("1.7.")) {        majorJavaVersion = 4;    } else if (javaVersion.contains("1.6.")) {        majorJavaVersion = 3;    } else {        majorJavaVersion = 2;    }}
