JdbcTemplate - SQLWarning ignored: SQL state '22007', error code '1292', message [Truncated incorrect DOUBLE value: 'stepExecutionContext[toId]']

问题:

I am simply developing the Spring Batch partitioned code looking at http://www.mkyong.com/spring-batch/spring-batch-partitioning-example/ and already went through the link : Error Code 1292 - Truncated incorrect DOUBLE value - Mysql but it did not solved my purpose.

I have the following bean

<bean id="pagingItemReader" class="org.springframework.batch.item.database.JdbcPagingItemReader" scope="step">         <property name="dataSource" ref="dataSource" />         <property name="pageSize" value="200" />          <property name="queryProvider">             <bean class="org.springframework.batch.item.database.support.SqlPagingQueryProviderFactoryBean">                 <property name="dataSource" ref="dataSource" />                 <property name="selectClause" value="SELECT customerNumber, checkNumber,paymentDate,amount" />                 <property name="fromClause" value="FROM classicmodels.payments" />                 <property name="whereClause" value="${payments.query.where.clause}" />                 <property name="sortKey" value="customerNumber" />             </bean>         </property>         <!-- Inject via the ExecutionContext in rangePartitioner -->         <property name="parameterValues">             <map>                 <entry key="fromId" value="stepExecutionContext[fromId]" />                 <entry key="toId" value="stepExecutionContext[toId]" />             </map>         </property>         <property name="rowMapper">             <bean class="com.prateek.mapper.PaymentsRowMapper" />         </property>     </bean> 

Getting below error:

回答1:

The error happens because the value stepExecutionContext[fromId] is not evaluated as a SpEL expression and goes raw (as is) to the database server.

The example you linked to uses the correct syntax: <entry key="fromId" value="#{stepExecutionContext[fromId]}" /> but in your example you have: <entry key="fromId" value="stepExecutionContext[fromId]" /> without the #{...}.

Even though the syntax in the example of mkyong is correct, I would recommend using simple quotes around keys in the execution context (<entry key="fromId" value="#{stepExecutionContext['fromId']}" />) as it is mentioned in the official documentation here: https://docs.spring.io/spring-batch/4.0.x/reference/html/step.html#late-binding
