利用spring中的ServletContextAware 接口获得ServletContext ，从而获得服务器上下文路径

程序片段：

package com.ahtec.oa.service.impl;</p> <p>import java.io.File;<br /> import java.io.IOException;</p> <p>import javax.servlet.ServletContext;</p> <p>import org.apache.commons.io.FileUtils;<br /> import org.slf4j.Logger;<br /> import org.slf4j.LoggerFactory;<br /> import org.springframework.stereotype.Component;<br /> import org.springframework.web.context.ServletContextAware;</p> <p>/**<br /> * @author Wu<br /> */<br /> @Component<br /> public class AutoRunServiceImpl implements ServletContextAware {</p> <p> protected final Logger logger = LoggerFactory.getLogger(this.getClass());</p> <p> private ServletContext servletContext;</p> <p> public void setServletContext(ServletContext servletContext) {<br /> this.servletContext = servletContext;<br /> }</p> <p> public void deletePdcaZipFile() {<br /> logger.debug("start deletePdcaZipFile ...");<br /> String pdcaDeleteFileLocation = "";<br /> try {<br /> String fileLocation = "files//pdca//";<br /> String ctxDir = this.servletContext.getRealPath(String.valueOf(File.separatorChar));<br /> if (!ctxDir.endsWith(String.valueOf(File.separatorChar))) {<br /> ctxDir = ctxDir + File.separatorChar;<br /> }<br /> pdcaDeleteFileLocation = ctxDir + fileLocation;<br /> FileUtils.deleteDirectory(new File(pdcaDeleteFileLocation));<br /> logger.debug("has deleted : '{}' all files!", pdcaDeleteFileLocation);<br /> logger.debug("end deletePdcaZipFile...");<br /> } catch (IOException e) {<br /> logger.debug("do not find pdcaDeleteFileLocation: {}", pdcaDeleteFileLocation);<br /> }<br /> logger.debug("============================================================");<br /> }</p> <p>}<br />
