一、异常描述

通过DBUtilExt工具类进行实现文本大字段读取readTemCLOB的时候，报“java.sql.SQLException: 违反协议”异常，详细错误日志如下>>

java.sql.SQLException: 违反协议@b@	at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)@b@	at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)@b@	at oracle.jdbc.dbaccess.DBError.check_error(DBError.java:1160)@b@	at oracle.jdbc.ttc7.Ocommoncall.receive(Ocommoncall.java:149)@b@	at oracle.jdbc.ttc7.TTC7Protocol.setAutoCommit(TTC7Protocol.java:538)@b@	at oracle.jdbc.driver.OracleConnection.setAutoCommit(OracleConnection.java:1220)@b@	at com.xwood.engine.common.util.DBUtilExt.readTemCLOB(DBUtilExt.java:71)@b@	at com.xwood.engine.publisher.master.TinContentMapProcesserHandler.addclob(TinContentMapProcesserHandler.java:37)@b@	at com.xwood.engine.publisher.master.TinContentMapProcesserHandler.addclob(TinContentMapProcesserHandler.java:28)@b@	at com.xwood.engine.publisher.master.TinContentMapProcesserHandler.add(TinContentMapProcesserHandler.java:71)@b@	at com.xwood.engine.publisher.core.processunit.S3PEntityRedisProcessUnit.setTargetobj(S3PEntityRedisProcessUnit.java:161)@b@	at com.xwood.engine.publisher.core.processunit.S3PEntityRedisProcessUnit.run(S3PEntityRedisProcessUnit.java:71)@b@	at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:439)

二、解决办法

根据错误日志提示找到抛异常入口代码“conn2.setAutoCommit(false);”,改为true或注释掉该行，解决问题。
