我有一个字符串||81|||01||,我想用|符号分割字符串.

我这样做了,

String str = "||81|||01||";
System.out.println(str .split("\\|").length); //printing 6 . But I am expecting 8

这段代码有什么问题？| 如何将该字符串与该字符分开,以便获得预期的length(8)？

Jboss 7默认使用infinispan 5.2.我如何将其迁移到最新infinispan 6版本？

我正在尝试在我的应用程序中使用Jboss AS托管Infinispan,以便我可以使用Jboss Admin console它来管理它.我已经尝试了基于Infinispan文档的以下步骤,

1)创建了一个名为Config的类

import javax.annotation.Resource;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Produces;

import org.infinispan.manager.EmbeddedCacheManager;

public class Config {
    @Produces
    @ApplicationScoped
    @Resource(lookup = "java:jboss/infinispan/test")
    private EmbeddedCacheManager defaultCacheManager;

    public void printObject() {
        System.out.println("defaultCacheManager:" + defaultCacheManager);
    }
}

2)创建一个servlet只是为了制作Config对象并调用printObject()方法

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestServlet extends HttpServlet {

    /** 
    * 
    */
    private static final long serialVersionUID = 3200037917839533696L;

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doIt(req, resp); …
