解决方案
解决方案二：
打开oracle驱动的jar里面的MANIFEST.MF清单文件看，这个jar包是不是已经经过数字签名，并且Sealed:true如果Sealed:true那么这个jar里面的javapackage列表中的所有类，如果在这个jar文件之外也有其它类在这些javapackage中的话就会出错，再加上数字签名就能防止其它人弄一个类往你的javapackage名字空间里面混淆替换，篡改原来的jar文件。你这个CGLIB增强在它看来属于篡改行为。
解决方案三：
Manifest-Version:1.0Specification-Title:OracleJDBCdriverclassesforusewithJDK14Sealed:trueCreated-By:1.4.2_08(SunMicrosystemsInc.)Implementation-Title:ojdbc14.jarSpecification-Vendor:OracleCorporationSpecification-Version:OracleJDBCDriverversion-"10.2.0.1.0"Implementation-Version:OracleJDBCDriverversion-"10.2.0.1.0"Implementation-Vendor:OracleCorporationImplementation-Time:WedJun2211:19:452005Name:oracle/sql/converter/Sealed:falseName:oracle/sql/Sealed:falseName:oracle/sql/converter_xcharset/Sealed:false
解决方案四：
上面这个是MANIFEST.MF清单。Sealed:true下面我应该怎么做呢
解决方案五：
把这个jar解压后重新打包成不带签名和sealed试试看，反正你是自己用的，又不是像Oracle那样发布产品出去。
