MAVEN 绑定SVN 版本号，并在web app中使用

在SVN 中的版本号， 如果需要使用，可以通过maven 插件注入到配置文件中，并在webapp启动时注入到应用中

plugin:

 org.codehaus.mojo
 buildnumber-maven-plugin
 1.0
 
      
           validate
           
                create
           
      
 
 
      false
      false
      
          javasvn
      
 
 
      
           com.google.code.maven-scm-provider-svnjava
           maven-scm-provider-svnjava
           2.0.2
      
      
           org.tmatesoft.svnkit
           svnkit
           1.8.6
      
 

 原理是使用javasvn provider 来访问SVN

然后在src/main/resources 下面添加一个build.properties

build.properties:
build.version=${version}  # Maven version
build.revision=${buildNumber} # Source code revision number 
build.timestamp=${timestamp} # long value of check in time

这样在build之后，信息会添加到properties中

build.properties:
build.version=1.2.3
build.revision=9876
build.timestamp=12345459

 使用：

public class PageRequestInterceptor extends HandlerInterceptorAdapter {

@Value(“${build.version}”)
private String buildVersion;

@Value(“${build.revision}”)
private String buildRevision;

private DateTime buildTimestamp;

@Value(“${build.timestamp}”)
public void setBuildTimestamp(String timestamp) {
buildTimestamp = new DateTime(Long.parseLong(timestamp));
}

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

request.setAttribute(“buildVersion”, buildVersion);
request.setAttribute(“buildRevision”, buildRevision);
request.setAttribute(“buildDateTime”, buildTimestamp);

 

这里还有一个问题，每次eclipse自动编译的时候，会把这些配置覆盖，所以需要添加一个plguin来把这些exclude

在POM中添加：

 
 
      
           org.eclipse.m2e
           lifecycle-mapping
           1.0.0
           
                
                     
                        
                            
                            org.codehaus.mojo
                            buildnumber-maven-plugin
                            [1.0,)
                            
                                create
                            
                            
                            
                                
                                  true
                                
                            
                       
                
             
          
      
   
 

 

添加之后可以通过右键project->MAVEN->Lifecycle Mapping来验证
