java - Spring Mail Generating Null Pointer exception -

i'm trying configure mail service in spring , maintain getting null pointer exception. suspicion can't find "mailsender" bean way off. configuration follows:

web.xml

<!-- processes application requests --> <servlet> <servlet-name>appservlet</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <param-name>logverbositylevel</param-name> <param-value>error</param-value> </init-param> <init-param> <param-name>contextconfiglocation</param-name> <param-value>/web-inf/spring/appservlet/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>

yu need set configurations in test class, whould re-create context file root of test class (just file resolution, when spring runners starts needs load context file)..your test class should this...

import org.junit.test; import org.junit.runner.runwith; import org.springframework.beans.factory.annotation.autowired; import org.springframework.test.context.contextconfiguration; import org.springframework.test.context.junit4.springjunit4classrunner; import org.springframework.test.context.web.webappconfiguration; @runwith(springjunit4classrunner.class) @contextconfiguration(locations = { "applicationcontext.xml" }) @webappconfiguration public class facadetest { private string phonenumber = "111111115"; @autowired private bussinesdelegate bussinesdelegate; @test public void runtest(){ this.fulltest(phonenumber, "aaaaa"); } public void fulltest(string phonenumber, string answer){ seek { bmoabussinesdelegate.processmessage("127.0.0.1", phonenumber, "camicase" + system.currenttimemillis()); } grab (exception e) { // todo auto-generated grab block e.printstacktrace(); } }

and dont forget check dependencies!

<!-- junit --> <dependency> <groupid>junit</groupid> <artifactid>junit</artifactid> <version>4.11</version> <scope>test</scope> </dependency> <!-- testng --> <dependency> <groupid>org.testng</groupid> <artifactid>testng</artifactid> <version>6.8.5</version> <scope>test</scope> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-test</artifactid> <version>${spring.version}</version> </dependency>

the cool thing spring, its ioc container can probide same behavior total java ee compliant server without needing server, , runner load context manually, same way ir in standole app spring ;)
