Please Help in Migration from old spring to new 3.1

[raja_s_patil]

Hello,

I have developed a Flex-spring-mybatis-Firebird application couple of years ago with 3.0 and is working fine.
Few weeks ago I have started developing another application on same platform but this time I decided to use new spring 3.1.

so I installed STS 2.8.1, got latest libs like apache-commons, Joda datetime, dozer, myBatis 3.0.6, mybatis spring and Spring 3.1, sec 3.1, spring-flex 1.5. Created jsp pages for general info and as flex container. copied config files from old application and edited headers and contents suitable to 3.1 in STS till editor stops showing errors. Then I tried to deploy it on STS vfabric TC 2.6 till this time no java beans have been developed for application functionality since System Study phase is in progress, I am trying to test loading of web pages by in memory authentication and check authorizations for web pages only, services are not yet developed. My application is not getting started and TC server throws exception. The config file under consideration is as follows.

<?xml version="1.0" encoding="UTF-8"?>

The TC server throws exception that place holder "mapper.ClassPackages" not found.


Can somebody help me in this ?

Thanks and warm regards.

Well, it's obviously not finding the properties file. You might be better off installing the properties file in WEB-INF/classes, like in "WEB-INF/classes/spring/appl-myBatis-Reference.properties", and then changing your "location" value to "classpath:spring/appl-myBatis-Reference.properties".

[raja_s_patil]

Thanks dkarr,

with your suggestion previous error has gone but still it is throwing exception as follows.
hope you could throw some light on this.

But I wonder my previous config was able to load properties from web-inf/spring/*
is there any change in spring 3.1 ?

Thanks and warm regards.

[raja_s_patil]

Sorry friends,

I figured out why this was happening, a springframework-bean.jar from ver 3.0 was in lib folder I deleted it and the original error popped back.
I have modified the xml as below and also attaching debug log. Still its not able to locate the properties file.

Please help me out

Thanks and warm regards.

[dkarr]

Does your deployment package have the exact element path of "WEB-INF/classes/properties/appl-myBatis-Reference.properties"?

[raja_s_patil]

Thanks dkarr,

I figured out what is happening. First I modified the appl-myBatis-Spring-Config.xml as below

<bean id="myBatisProperties" class="org.springframework.context.support.Propert ySourcesPlaceholderConfigurer">
<property name="location" value="classpathroperties/appl-myBatis-Reference.properties"/>
</bean>

<!-- Datasource for Database using Connectivity Parameters -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>

<!-- connection Pool Parameters -->
<property name="maxActive" value="${pool.maxActive}"/>
<property name="maxIdle" value="${pool.maxIdle}"/>
<property name="minIdle" value="${pool.minIdle}"/>
<property name="initialSize" value="${pool.initialSize}"/>
<property name="maxWait" value="${pool.maxWait}"/>
</bean>

<!-- Define Transaction Manager -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSou rceTransactionManager">
<property name="dataSource"><ref local="dataSource"/></property>
</bean>

<!-- Define How Transaction Manager is Used -->
<tx:annotation-driven transaction-manager="transactionManager" />

<bean id="myBatisMapperScanner" class="org.mybatis.spring.mapper.MapperScannerConf igurer">
<property name="basePackage" value="com.tej_EIS.mbMappers" />
(The actual value instead of place holder)
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" value="${myBatis.XmlLocations}" />
</bean>

Then studied the debug log as below

08:40:18 231 INFO Root WebApplicationContext: initialization started

So all main config xmls metioned in web.xml are being processed

And This is where things are going wrong. I was expecting that bean 'myBatisProperties' will be created before bean 'myBatisMapperScanner' but its getting created after it. so naturally placeholder ${myBatis.ClassPackages} was not available for bean 'myBatisMapperScanner'. Hence onward it was able to resolve placeholders like 'jdbc.driverClassName', 'jdbc.url' etc. etc. and application runs flawlessly.

Now I am searching documentation to find out how can I force spring to create beans in desired order. If you know it offhand please tell me how can I force spring to create bean 'myBatisProperties' before bean 'myBatisMapperScanner', so that I can continue using the properties file for all parameters.

Thanks and warm regards

dkarr,

I figured out how to control creation order of beans and tested it but spring is behaving differently than expected.

I modified the bean definition as follows

<bean id="myBatisProperties" class="org.springframework.context.support.Propert ySourcesPlaceholderConfigurer">
<property name="location" value="/WEB-INF/spring/appl-myBatis-Reference.properties"/>
<property name="localOverride" value="true"/>
</bean>

<bean id="myBatisMapperScanner" class="org.mybatis.spring.mapper.MapperScannerConf igurer" depends-on="myBatisProperties">
<property name="basePackage" value="com.tej_EIS.mbMappers" />
</bean>

it worked fine, bean "myBatisProperties" was created before bean "myBatisMapperScanner" as expected.
Also means that location /WEB-INF/spring/appl-myBatis-Reference.properties is accessible and it can pickup properties from it.
No problems at all.

Now I modified bean "myBatisMapperScanner" as follows

<bean id="myBatisMapperScanner" class="org.mybatis.spring.mapper.MapperScannerConf igurer" depends-on="myBatisProperties">
<property name="basePackage" value="${myBatis.ClassPackages}" />
</bean>

The trouble started once again the debug log is as follows

12:19:02 931 INFO Root WebApplicationContext: initialization started

12:19:04 725 DEBUG Loaded 8 bean definitions from location pattern [/WEB-INF/spring/appl-myBatis-Spring-Config.xml]

here [localproperties] is not being searched as it does for other beans. It seems that [localproperties] are not added
to search process. So I modify bean 'myBatisMapperScanner' as follows

<bean id="myBatisMapperScanner" class="org.mybatis.spring.mapper.MapperScannerConf igurer" depends-on="myBatisProperties">
<property name="basePackage" value="com.tej_EIS.mbMappers" />
</bean>

You can see that bean 'myBatisProperties' is cached after initializing bean 'myBatisMapperScanner' and
[localproperties] are added to search so the beans initializing after bean 'myBatisMapperScanner'
the [localproperties] are searched on first priority and all keys are found. Please refer below.

with few other experiments I have reached to conclusion that the [localProperties] are added to search only after
creating any bean after 'myBatisProperties' and properties are not available to initiazation of that bean but beans
following next, the [localProperties] are available.

Can you tell me what is happening and if possible solution to this. Timebeing, I am continuing my work with the
lame solution of defining fixed value in bean 'myBatisMapperScanner', with which application is running.

Thanks and warm regards

Raja.

Hi Raja. Have a look at this

Thanks mac1929,

The limping solution as mentioned above is working but As suggested in your link,
I am going for 1.1 and 3.1 versions soon. hope they have fixed the issue completely.

Thanks once again and warm regards.
