问题原因：

根本原因是JDK版本（1.8）与spring版本（2.5.6）之间不兼容的问题。org.springframework.context.annotation. AnnotationConfig BeanDefinitionParser会自动检测jdk的版本，检测时需要jre1.5以上版本，但是JdkVersion只检查到了1.7，jre1.8 时不匹配任何jdk。

解决办法：

1、降低jdk的版本

2、修改spring-2.5.6.jar的源码

① 在项目中创建一个package为org.springframework.core

② 在该package下面新建JdkVersion.java，内容如下：

package org.springframework.core;

public abstract class JdkVersion {
    public static final int JAVA_13 = 0;
    public static final int JAVA_14 = 1;
    public static final int JAVA_15 = 2;
    public static final int JAVA_16 = 3;
    public static final int JAVA_17 = 4;
    //for jre 1.8
    public static final int JAVA_18 = 5;
    private static final String javaVersion = System
            .getProperty("java.version");
    private static final int majorJavaVersion;
    public static String getJavaVersion() {
        return javaVersion;
    }
    public static int getMajorJavaVersion() {
        return majorJavaVersion;
    }
    public static boolean isAtLeastJava14() {
        return true;
    }
    public static boolean isAtLeastJava15() {
        return getMajorJavaVersion() >= 2;
    }
    public static boolean isAtLeastJava16() {
        return getMajorJavaVersion() >= 3;
    }
    static {
        //for jre 1.8
        if (javaVersion.indexOf("1.8.") != -1) {
            majorJavaVersion = 5;
        }else 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;
        }
    }
}

③ 到项目的WEB-INF/classes 下面找到对应的package中的JdkVersion.class文件
④ 将项目中的spring-core-2.5.6.jar拷贝出来打开，然后将JdkVersion.class替换jar包中的该文件。

⑤ 将修改后的spring-core-2.5.6.jar再覆盖到项目中即可。

3、在spring-2.5.6jar的org\springframework\core\下有JdkVersion.class这个类，同时在spring-core.4.2.0.RELEASE也有这个类，所以在引入jar包的时候不需要引入spring-2.5.6jar只引入spring-core.4.2.0.RELEASE就行了
