無法確定拋出異常的無效字符在哪里

以下是查詢字符串：

<sql:setDataSource var="orcl" driver="oracle.jdbc.driver.OracleDriver"
     url="jdbc:oracle:thin:@192.168.6.132:1521:orcl"
     user="jsp" password="jsp"/>

<sql:query dataSource="${orcl}" var="result">
SELECT * from Employees;
</sql:query>

Answer 1

分號是一個語句分隔符。 當您通過JDBC（或OCI等）執行語句時，不應該包含它，這是后台發生的事情。

所以你現在執行這個：

<sql:query dataSource="${orcl}" var="result">
SELECT * from Employees;
</sql:query>

將其更改為：

<sql:query dataSource="${orcl}" var="result">
SELECT * from Employees
</sql:query>
