windows操作系统下  之前通过shutdown.bat  最后发现根本杀不死tomcat相关的进程

try {
    			boolean check=true;
    			Properties props=System.getProperties(); //获得系统属性集    
    			String osName = props.getProperty("os.name"); //操作系统名称    
    			if(osName!=null&&osName.contains("Window")){
    				check=true;
    			}else{
    				check=false;
    			}
    			if(check){//windows
    			    String location = System.getenv("CATALINA_HOME");
     		         executeCmd(location); 
    				
    			}else{//linux
    				String commands="killall java";
    				Runtime runtime = Runtime.getRuntime();
    				Process pro = runtime.exec(commands);
    				pro.waitFor();
    				commands="/**/**/apache-tomcat-7.0.65/bin/startup.sh";
    				pro = runtime.exec(commands);
    				pro.waitFor();
    			 
    			}
    		} catch(Exception e){
    			return "fail";
    		}
    		return "success";

private static void executeCmd(String location) {  
    	        System.out.println(location);  
    	        Runtime run = Runtime.getRuntime();  
    	        try {  
    	            Process ps = run.exec("" + location + "\\bin\\shutdown.bat");  
    	             
     	            BufferedReader br = new BufferedReader(new InputStreamReader( ps.getInputStream(), "utf-8"));// 注意中文编码问题  
     	            String line;  
    	            while ((line = br.readLine()) != null) {  
    	                System.out.println("StartedLog==>" + line);  
    	            }
       	            br.close();  
       	            
     	        } catch (Exception e) {  
    	            e.printStackTrace();  
    	        }  
     	     
    	    }

最后发现杀不死tomcat进程

改进后：我直接通过tomcat 的端口号 根据端口号去查找所有与之相关的进程 然后在杀死

private Set<Integer> ports;//在类名下方定义一个变量

try {
    			//关闭quartz任务；
    			Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
      			scheduler.shutdown();
       			Thread.sleep(2000);
    			boolean check=true;
    			Properties props=System.getProperties(); //获得系统属性集    
    			String osName = props.getProperty("os.name"); //操作系统名称    
    			if(osName!=null&&osName.contains("Window")){
    				check=true;
    			}else{
    				check=false;
    			}
    			if(check){
                    //这里是Tomcat端口好 我这边是写死了，这也可以通过代码获取
     			    String port[]={"10012"};
    			    killPort(port);
      			}else{
    				String commands="killall java";
    				Runtime runtime = Runtime.getRuntime();
    				Process pro = runtime.exec(commands);
    				pro.waitFor();
    				commands="/**/**/apache-tomcat-7.0.65/bin/startup.sh";
    				pro = runtime.exec(commands);
    				pro.waitFor();
    				 
    			}
    		} catch(Exception e){
    			return "fail";
    		}
    		return "success";
