使用Spring Integration JDBC出站網關更新數據

Question

我需要有關Spring Integration jdbc出站網關的幫助。 我目前正在使用spring集成示例jdbc。 我添加了代碼來使用jdbc出站網關更新數據，這是spring-integration-context.xml：

Person.java POJO：

public class Person implements Serializable {

    private int personId;
    private String name;
    private Gender gender;
    private Date dateOfBirth;



    /**

請幫助我，我不知道哪個java.lang.Object，因為我不在代碼中的任何地方使用它。 謝謝

您錯過了UPDATE的id ：

<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> 

另外，該UPDATE上的SELECT需要一個單獨的ExpressionEvaluatingSqlParameterSourceFactory ：

<bean id="updateReplySource"
      class="org.springframework.integration.jdbc.ExpressionEvaluatingSqlParameterSourceFactory">
    <property name="parameterExpressions">
        <map>
            <entry key="id" value="payload.personId"/>
        </map>
    </property>
</bean>
