【急求】SPRING配置DATASOURCE,tomcat启动无错，weblogic启动报错
--------------------编程问答-------------------- 先把内容写死，不读property文件，可能是property文件没有加载到。 --------------------编程问答-------------------- 那就奇怪了，开始我也怀疑过，如果把这个注释掉，另外一个datasource是好用的 --------------------编程问答-------------------- 你的META-INF下的两个xml文件，能贴出来看看否 --------------------编程问答--------------------我本地这个文件夹下没有文件，另外我不是服务器管理员，看不到。 --------------------编程问答-------------------- weblogic最恶心的是自己提供了很多开源jar，它优先加载的是自己的jar，回到导致各种冲突不过这个是可以更改的。我以前在weblogic下部署也是出现了很多问题，不过现在让我搭一套环境只须10分钟。。。。。。。。。。。。 --------------------编程问答--------------------
是不是因为weblogic没有加载jt400.jar这个包？导致找不到com.ibm.as400.access.AS400JDBCDriver --------------------编程问答-------------------- 但是你这个报错并非noclassfound神马的，很男断定 --------------------编程问答-------------------- 这是报空指针错误的那个类源码
package net.sourceforge.jdbclogger.spring;--------------------编程问答-------------------- 63行那里，不知道是取不到BEAN，还是取到BEAN了，找不到beanName --------------------编程问答-------------------- 顶顶。。。。。。。。。 --------------------编程问答-------------------- 帮顶顶。。。。。。。。。这东西找你组长帮弄下 --------------------编程问答-------------------- 你查看下 你的配置文件是不是有注释

加载spring的配置文件的时候，在配置文件中有注释的存在，这回影响weblogic读取配置文件，从而导致weblogic不能正常的加载web应用，导致失败 --------------------编程问答--------------------
有可能,如果是你的数据源不是全局的话,建议看看局部配置有没有对上,之前我配置xml的时候也出现注释导致不行,你可以把注释都去掉看看 --------------------编程问答--------------------
如果把出问题的datasource注释掉，发布是没有问题的
补充：Java , Web 开发
