spring2.5+JDK1.8报错的解决办法

转自：http://blog.csdn.net/zhaohuihua/article/details/50572861

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！

修改后的spring.jar下载地址：http://download.csdn.net/detail/frt007/9460343

// spring-2.5.5.jar
static {
    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.jar
static {
    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;
    }
}
