无法确定抛出异常的无效字符在哪里

以下是查询字符串：

<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

分号是一个语句分隔符。当您通过JDBC（或OCI等）执行语句时，不应该包含它，这是后台发生的事情。

所以你现在执行的地方是：

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

将其更改为：

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