Spring exports a jar package that can run

There is a recent need to resolve the issue of the MAVEN project import executable jar package, if the project does not contain spring, then use MVN assembly:assembly, details can refer to: http://www.cnblogs.com/liqiu/p/3816068.html

However, if you include spring, then this method is not feasible, error:

 for XML schema namespace

I have been on the internet for two days, this is a bug assembly. See also: http://jira.codehaus.org/browse/MASSEMBLY-360

It is said that the reason is that more than one jar package in spring contains Spring.handlers and Spring.schemas files, and assembly only the first encountered files into the jar package, the later encountered will skip.

The solution is to give up assembly, Use the shade plug-in to package. Specifies that spring.handlers and spring.schemas files are added append in the shade packaging configuration to ensure that the information of the two files in other spring jars is not omitted.

Here is a very simple example of a MAVEN project with only four files, in the code re-attachment:

3. Code examples

Package Com.service;import Org.springframework.stereotype.Service, @Servicepublic class UserService {public    String Finduser () {        return "find Liqiu";    }}

 Packagecom.exec;ImportOrg.springframework.context.support.GenericXmlApplicationContext;ImportCom.service.UserService; Public classMain { Public Static voidMain (string[] args)throwsinterruptedexception {genericxmlapplicationcontext context=NewGenericxmlapplicationcontext (); Context.setvalidating (false); Context.load ("Classpath:applicationContext.xml");        Context.refresh (); UserService UserService= Context.getbean (userservice.class);  while(true) {System.out.println (Userservice.finduser ()); Thread.Sleep (10000); }    }}

Run at command line: MVN package

The target directory will then produce a jar package: My-spring-app.jar

Run: Java-jar Target/my-spring-app.jar

Of course, you can also run this: Java-classpath Target/my-spring-app.jar com.exec.Main
