Spring JdbcTemplate throw 17004我插入的列类型无效

Question

我的Spring Boot应用程序中的这段代码非常简单，但它抛出：

<plugin>
    <groupId>com.lazerycode.jmeter</groupId>
    <artifactId>jmeter-maven-plugin</artifactId>
    <version>${jmeter.maven.plugin.version}</version>
    <executions>
        <!-- defines a runner for jmeter tests project -->
        <execution>
            <id>jmeter-tests</id>
            <phase>test</phase>
            <goals>
                <goal>jmeter</goal>
            </goals>
            <configuration>
                <resultsDirectory>${project.build.directory}/jmeter/results</resultsDirectory>
                <ignoreResultFailures>true</ignoreResultFailures>
                <suppressJMeterOutput>false</suppressJMeterOutput>
                <resultsFileFormat>xml</resultsFileFormat>
                <testResultsTimestamp>false</testResultsTimestamp>
                <appendResultsTimestamp>false</appendResultsTimestamp>
                <testFilesIncluded>
                    <jMeterTestFile>Service-Tests.jmx</jMeterTestFile>
                </testFilesIncluded>
                <jMeterProcessJVMSettings>
                    <arguments>
                        <argument>-Djavax.net.ssl.keyStore=jmeterTrustedKeystore.jks</argument>
                        <argument>-Djavax.net.ssl.keyStorePassword=changeit</argument>
                    </arguments>
                </jMeterProcessJVMSettings>
            </configuration>
        </execution>
    </executions>
</plugin>

以下是代码：

org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [INSERT INTO decisions_cache_log ( server_ip, server_hostname, cache_type, load_time) VALUES (?, ?, ?, ?)]; SQL state [99999]; error code [17004]; Invalid column type; nested exception is java.sql.SQLException: Invalid column type

此Oracle 10数据库中的所有四列都是VARCHAR2

谢谢...
