I test Mapper with JUnit, and I get the log info bellow infinite loop.
14:07:54.040 [main] DEBUG o.m.spring.SqlSessionFactoryBean - Property 'configLocation' not specified, using default MyBatis Configuration
This is just a information that you haven't included <property name="configLocation" value="path_to_mybatis_config_file.xml"/>.
Note that this message is not indicating any error, as it's not always neccessary to include this XML file, because some configuration can be performed directly using bean property tags.
In order for others to help you, please show your application context setup for org.mybatis.spring.SqlSessionFactoryBean. This is a working example:
<bean id="YOUR_BEAN_ID" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="YOUR_DATA_SOURCE"/>
<property name="mapperLocations" value="classpath*:*Mapper.xml"/>
<property name="configLocation" value="classpath:TO_YOUR_MYBATIS_CONFIG.XML"/>

I'm working on an existing Spring application that uses JDBC (DAO's extend NamedParameterJdbcDaoSupport). There were four datasources configured, each with it's own DataSourceTransactionManager. (though only one was registered with tx:annotation-driven for some reason)
I've recently added JPA (Spring-data-JPA) into the application and configured two entityManagerFactories (for now I don't need the other two datasources). I also configured two JpaTransactionManagers and removed the corresponding DataSourceTransactionManagers for these dataSources, since the JpaTransactionManagers can also be used for JDBC transactions. (correct me if I'm wrong)
It appears I need to be able to have distributed transactions, since the two datasources (to two different databases) need to be accessed (through JPA) in one service method. Since I did not have all I need to set up JTA (missing XA-driver for one of the databases) I've decided to give the Spring ChainedTransactionManager a try. Sadly this didn't work out as expected. All works fine if I just call a service method that only uses JPA.
Though when I call an existing service method that uses a JDBC find that has a class level #transactional annotation with it's propagation set to NOT_SUPPORTED and call another service method after that with a JPA call and a #transactional, I get an exception:
Caused by: java.lang.IllegalStateException: Already value [org.springframework.jdbc.datasource.ConnectionHolder#462cf9d9] for key [org.jboss.jca.adapters.jdbc.WrapperDataSource#3fbb4c32] bound to thread [http-/127.0.0.1:8080-5]
at org.springframework.transaction.support.TransactionSynchronizationManager.bindResource(TransactionSynchronizationManager.java:189) [spring-tx-3.2.5.RELEASE.jar:3.2.5.RELEASE]
at org.springframework.orm.jpa.JpaTransactionManager.doBegin(JpaTransactionManager.java:403) [spring-orm-3.2.5.RELEASE.jar:3.2.5.RELEASE]
After some debugging, I found out that the transactions in Spring get added to a map on a ThreadLocal in the "TransactionSynchronizationManager.bindResource" method. The problem is that when using a JDBC call with #transactional and propogation NOT_SUPPORTED, a transaction is made anyway and registered through that method. When the JpaTransactionManager tries to bind it's resource, it is already on the map (and not marked as void) which causes the error to occur.
Changing the propagation to the default "REQUIRED" for the service call that encapsulates the JDBC call fixes the problem.
I have no idea why Spring is still creating that transaction when the transactional annotation is NOT_SUPPORTED. And if it creates that transaction, it should not bypass the JpaTransactionManager.
So what I'd like to know is if there is some way to tell Spring to use the JpaTransactionManager also when it creates a transaction itself inside the NamedParameterJdbcDaoSupport. (Well actually the JdbcDaoSupport... Well actually the DataSourceUtils)
We're using Spring 3.2.5, spring-data-jpa 1.6.0 and I've used Hibernate 4.2.0 as JpaVendor.
This problem doesn't occur without the ChainedTransactionManager.

<property name="persistenceUnitName" value="mysqlPU"/>
<property name="jpaVendorAdapter" ref="jpaVendorAdapter"/>
<property name="jpaProperties">
<!-- properties -->
</property>
</bean>
For now I've "fixed" this, by changing all the class-level transactional annotations to have propagation.REQUIRED (default) instead of NOT_SUPPORTED. Though I do not really like this solutions, since it might be somebody set those propagations to NOT_SUPPORTED with a good reason. I've also tried SUPPORTED, but using that had the same issue as NOT_SUPPORTED: a transaction was being made anyway by the Spring DataSourceUtils when the query was being executed by the NamedParameterJdbcDaoSupport DAO.
When no transactional annotation is set on the service, all works well too.
I am upgrading Spring from Spring 2.x to Spring 4.2.4 and Quartz from 1.8 to 2.3
Following bean throws "Invalid property 'durability' of bean class [org.springframework.scheduling.quartz.SchedulerFactoryBean]"
If I remove the durability property, I get "org.quartz.SchedulerException: Jobs added with no trigger must be durable"
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="durability" value="true"/>
<property name="recover" value="false"/>
<property name="jobDetails">
<list>
<ref bean="deleteTempFileJobScheduler" />
</list>
</property>
<property name="triggers">
<list>
<ref bean="deleteTempFileJobSchedulerTrigger" />
</list>
</property>
</bean>
Any suggestion?
Thanks in advance.
A Quartz-Job has a attribute called durability.
This property determines whether a Job without triggers should automatically deleted.
I.e. if you set
<property name="durability" value="true"/>
than Jobs remain in the JobStore even if no triggers point to it anymore.
But if you set
<property name="durability" value="false"/>
than jobs should be removed from the JobStore if no triggers point to it.
In that case Quartz gives you the mentioned Exception if you try to add a Job without Triggers to the JobStore (since you add a Job which will be immediately removed).
To prevent such an Exception you could add a Job together with an Trigger to the JobStore.
You need set durability property to JobDetailFactoryBean
(in your case, this is deleteTempFileJobScheduler) and not to SchedulerFactoryBeam
When we are creating job itself , you can add storeDurably(true)
. It is work for me .
JobDetail job = newJob(JobScheduler.class)
.withIdentity( sc.getId()+ "_Job")
.usingJobData(getJobDataMap(sc))
.storeDurably(true)
.build();
I'm developping an application using spring and hibernate.
When I run my application I get this error message:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'transactionManager' is defined
In my context application file I have this :
<bean id="tansactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
I googled about the problem and I found a solution that I have to change this line :
<bean id="tansactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
By :
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
But I got another problem :
org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [org.springframework.orm.jpa.JpaTransactionManager]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
How can I solve this problem ?
You have a typo in your annotation "tansactionManager" is missing and 'r', "transactionManager". I made the correction and it worked just fine for me.
If you are using session factory, so this should work
<bean id="tansactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
but if you want to use JPA EntityManager, so you need
<bean name="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
Please refer to migrating-to-spring-3-1-and-hibernate-4-1 it contains nice example for the required configurations
I use restlet in camel route in from("restlet:http/myLink") clause. When user's requests more then ten per second, I begin recieve errors processing request like a "org.restlet.engine.connector.Controller run
INFO: Connector overload detected. Stop accepting new work"
I think, that error is caused by number of threads,request query's size or number,or something like that. I try set to maxThreads param different values in spring config
<bean id="restlet" class="org.apache.camel.component.restlet.RestletComponent">
<property name="maxThreads" value="15"/>
</bean>
but I am not succeed. In documentation http://camel.apache.org/restlet.html I ddin't find ant param for setting size\number of request queue. I need help :(
P.S. camel-restlet version is 2.12.2
Update
I try to set big numbers to maxThreads,maxConnectionsPerHost,maxTotalConnections, but it's useless. If inject org.restlet.Component to camel's config like that:
<bean id="restletComponent" class="org.restlet.Component" />
<bean id="restlet" class="org.apache.camel.component.restlet.RestletComponent">
<constructor-arg index="0">
<ref bean="restletComponent" />
</constructor-arg>
<property name="maxThreads" value="255"/>
<property name="maxConnectionsPerHost" value="1000"/>
<property name="maxTotalConnections" value="1000" />
</bean>
How I can override properties, that use BaseHelper params?
After go through the options of lowThread as well.
But I found current released camel doesn't support it.
I am working on a Spring WebFlow project which has a lot of property values in XML files, as any Spring programmer knows. I have database user names, password, URLs, etc.
We are using Eclipse with Spring WebFlow and Maven. We are trying to have an SA do the builds but the SA does not want to go into the XML files to change the values, but on the other hand, we don't know the production values. How do we work with this?
Most SA are more willing and confident to deal with .properties file rather than .xml.
Spring provide PropertyPlaceholderConfigurer to let you define everything into one or several .properties file and substitute the placeholder in applicationContext.xml.
Create a app.properties under src/main/resources/ folder:
... ...
# Dadabase connection settings:
jdbc.driverClassName=org.postgresql.Driver
jdbc.url=jdbc:postgresql://localhost:5432/app_db
jdbc.username=app_admin
jdbc.password=password
... ...
And use PropertyPlaceholderConfigurer in applicationContext.xml like so:
... ...
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>app.properties</value>
</property>
</bean>
... ...
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
Check out Spring PropertyPlaceholderConfigurer Example for more details.
In addition, from application deployment perspective, we usually package app in some executable format and the .properties files are usually packed inside the executable war or ear file. A simple solution is to configure your PropertyPlaceholderConfigurer bean to resolve properties from multiple location in a pre-defined order, so in the deployment environment, you can use a fixed location or environment variable to specify the properties file, also note that in order to simplify the deploy/configure task for SA, we usually use a single external .properties file define all runtime configuration, like so:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<!-- Default location inside war file -->
<value>classpath:app.properties</value>
<!-- Environment specific location, a fixed path on server -->
<value>file:///opt/my-app/conf/app.properties</value>
</list>
</property>
<property name="ignoreResourceNotFound" value="true"/>
</bean>
Hope this helps.
Another simple way is Spring Expression Language (SpEL)
for example
<property name="url" value="#{ systemProperties['jdbc.url'] }" />
Documentation
spring documentations
Also you can define a propertyConfigurer programmatically in configuration class:
#Configuration
#PropertySource("classpath:application.properties")
public class PropertiesConfiguration {
#Bean
public PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer(Environment env) {
PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
configurer.setEnvironment(env);
return configurer;
}
}
