I want to create XMPP connection with security, I tried this
<bean id="xmppConnection" class="o.s.i.xmpp.XmppConnectionFactoryBean">
<constructor-arg>
<bean class="org.jivesoftware.smack.ConnectionConfiguration">
<constructor-arg value="myServiceName"/>
<property name="truststorePath" value="..."/>
<property name="socketFactory" ref="..."/>
</bean>
</constructor-arg>
</bean>
dependencies
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
compile("org.springframework.integration:spring-integration-xmpp:4.3.8.RELEASE")
testCompile("junit:junit")
}
But class o.s.i.xmpp.XmppConnectionFactoryBean not found. Do I need to include any other dependency.
The package is abbreviated because of formatting for the documentation. The actual class name is
org.springframework.integration.xmpp.config.XmppConnectionFactoryBean
This is explained in the documentation.
1. Conventions in this Book
In some cases, to aid formatting, when specifying long fully-qualified class names, we shorten the package org.springframework to o.s and org.springframework.integration to o.s.i, such as with o.s.i.transaction.TransactionSynchronizationFactory.
If you use IDE content assist (eclipse, IDEA) when typing class names, it will complete the package for you.

i build async jersey web services, and now i need to make some operations with ldap.
I have configure Spring beam.xml in this mode:
<bean id="contextSourceTarget" class="org.springframework.ldap.core.support.LdapContextSource">
<property name="url" value="${ldap.url}" />
<property name="base" value="${ldap.base}" />
<property name="userDn" value="${ldap.userDn}" />
<property name="password" value="${ldap.password}" />
<property name="pooled" value="false" />
</bean>
<bean id="contextSource"
class="org.springframework.ldap.pool.factory.PoolingContextSource">
<property name="contextSource" ref="contextSourceTarget" />
</bean>
<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
<constructor-arg ref="contextSource" />
</bean>
<bean id="ldapTreeBuilder" class="com.me.ldap.LdapTreeBuilder">
<constructor-arg ref="ldapTemplate" />
</bean>
<bean id="personDao" class="com.me.ldap.PersonDaoImpl">
<property name="ldapTemplate" ref="ldapTemplate" />
</bean>
But when i try to use ldap i have this error:
Error creating bean with name 'contextSource' defined in class path resource [config/Beans.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/pool/KeyedPoolableObjectFactory
In my project i have commons-pool2-2.2.jar lib, but still i have this error..i try to add commons-pool2-2.2.jar in TOMCAT_PATH/lib but not works..
UPDATE:
If i put commons-pool-1.6.jar it works.. but if i want to use pool2 how i can do? only i must change class inn commons-pool2-2.2.jar?
Updated Answer:
Since at least Spring LDAP 2.3.2 you can now use commons-pool2. Spring LDAP now provides two classes:
For commons-pool 1.x:
org.springframework.ldap.pool.factory.PoolingContextSource
For commons-pool 2.x:
org.springframework.ldap.pool2.factory.PooledContextSource
Details can be found here:
https://github.com/spring-projects/spring-ldap/issues/351#issuecomment-586551591
Original Answer:
Unfortunately Spring-Ldap uses commons-pool and not commons-pool2. As you have found the class org.apache.commons.pool.KeyedPoolableObjectFactory does not exist in commons-pool2 (it has a different package structure), hence the error.
There is a Jira issue for the Spring-ldap project asking them to upgrade/support commons-pool2:
https://jira.spring.io/browse/LDAP-316
Until that has been completed you will have to use commons-pool 1.6.
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 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"/>
</bean>
How can I create bean definition of multiple classes in spring? I know the spring TS helps to create bean definition but can it used to create for multiple classes at one time?
<bean id="class1" class="com.test.Class1">
</bean>
<bean id="class2" class="com.test.Class2">
</bean>
<bean id="class3" class="com.test.Class3">
</bean>
Yes, following bean configuration file is perfectly valid:
<bean id="class1a" class="com.test.Class1">
</bean>
<bean id="class1b" class="com.test.Class1">
</bean>
You will get 2 instances of Class1 with different bean name. You just need to be careful when autowiring (esp. by type)
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;
}
}
