好吧，weblogic的问题确实……
问题一：
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: URL [zip:E:/weblogic/user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_user/_appsdir_scrcu_kstrap_war/a4dr3u/war/WEB-INF/lib/_wl_cls_gen.jar!/com/kayak/util/cache/loader/xxxxxx.class]; nested exception is java.lang.ArrayIndexOutOfBoundsException: 768

【解决】首先这个异常真是让我很。。查看错误日志，并非web项目的问题，而且该web项目在tomcat当中部署得很正常啊。。又看到有 java.lang.ArrayIndexOutOfBoundsException:更是让人一头雾水。试了网上所说的设置weblogic的内存之类，自己又用jd-gui.exe 去看底层jar包追踪错误源，但是还是一筹莫展。。
看到错误日志第一行红色部分，应该是未正确加载到xxx.class所致，跟踪:E:/weblogic/user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_user/_appsdir_scrcu_kstrap_war/a4dr3u/war/WEB-INF/lib/_wl_cls_gen.jar，jd-gui.exe打开_wl_cls_gen.jar包，发现xxx.class确实是// INTERNAL ERROR //的错误（未正确解析）；但发现项目启动并未指定要用到xxx.java啊。。
后来，换了一种文件形式，用WebRoot放在autodeploy下，这下终于可以正常部署了！！
至于为啥用war包不行（有的工程可以，但不知道这个工程为何不行）我也不知道原因。。
——注意到，E:/weblogic/user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_user下会有一些临时文件。通过war包部署时，会自动生成一个名为_wl_cls_gen.jar的jar包；而通过WebRoot（或者说war包的解压文件）部署时，则不会有该jar包。。
当有的项目通过war包的方式部署失败，并出现Caused By: java.lang.ArrayIndexOutOfBoundsException这个奇怪的异常时，不妨改成它的解压文件形式部署，说不定可以成功。
