使用 Spring 集成 JDBC 出站网关更新数据
Update Data Using Spring Integration JDBC Outbound Gateway
我需要有关 spring 集成 jdbc 出站网关的帮助。我目前正在玩 spring 集成示例 jdbc。我添加代码以使用 jdbc 出站网关更新数据，这里是 spring-integration-context.xml：

请帮助我，我不知道哪个 java.lang.Object，因为我没有在代码中的任何地方使用它。谢谢
您错过了 id UPDATE:
<bean id="requestSource" class="org.springframework.integration.jdbc.ExpressionEvaluatingSqlParameterSourceFactory">
<property name="parameterExpressions">
<map>
<entry key="id" value="payload.personId"/>
<entry key="name" value="payload.name.toUpperCase()"/>
<entry key="gender" value="payload.gender.identifier"/>
<entry key="dateOfBirth" value="payload.dateOfBirth"/>
</map>
</property>
</bean>
此外，UPDATE 上的 SELECT 需要一个单独的 ExpressionEvaluatingSqlParameterSourceFactory :
<bean id="updateReplySource"
class="org.springframework.integration.jdbc.ExpressionEvaluatingSqlParameterSourceFactory">
<property name="parameterExpressions">
<map>
<entry key="id" value="payload.personId"/>

请帮助我，我不知道哪个 java.lang.Object，因为我没有在代码中的任何地方使用它。谢谢
您错过了 id UPDATE:
<bean id="requestSource" class="org.springframework.integration.jdbc.ExpressionEvaluatingSqlParameterSourceFactory">
<property name="parameterExpressions">
<map>
<entry key="id" value="payload.personId"/>
<entry key="name" value="payload.name.toUpperCase()"/>
<entry key="gender" value="payload.gender.identifier"/>
<entry key="dateOfBirth" value="payload.dateOfBirth"/>
</map>
</property>
</bean>
此外，UPDATE 上的 SELECT 需要一个单独的 ExpressionEvaluatingSqlParameterSourceFactory :
<bean id="updateReplySource"
class="org.springframework.integration.jdbc.ExpressionEvaluatingSqlParameterSourceFactory">
<property name="parameterExpressions">
<map>
<entry key="id" value="payload.personId"/>
</map>
</property>
</bean>
