我使用nutz对微信开发提供包,然后按规定写了配置文件,也成功注入 private WxApi2 wxApi; 然后我调用wxApi.getJsapiTicket(); 发生了空指针:

我跟入getJsapiTicket方法,发现这句抛出异常,

WxJsapiTicket at = jsapiTicketStore.get();

断点查看后 发现 protected WxJsapiTicketStore jsapiTicketStore; 为null,难道是需要我手动给他搞出来?

嗯，设置一下吧

所以咋设置......

恩, 应该添加个默认值

好了,提交了

所以呢....

我是应该去下载新的包么

mvn的话, force update一下完事

版本号变了么?

我的maven坐标为:

<dependency>
            <groupId>org.nutz</groupId>
            <artifactId>nutzwx</artifactId>
            <version>1.r.61.r2</version>
        </dependency>

开始是1.r.60来着,然后换了下最新的,然后我看到相关代码有所改动

  public String getJsapiTicket() {
        WxJsapiTicket at = this.jsapiTicketStore.get();
        if(at == null || (long)at.getExpires() < (System.currentTimeMillis() - at.getLastCacheTimeMillis()) / 1000L) {
            Object var2 = this.lock;
            synchronized(this.lock) {
                WxJsapiTicket at_forupdate = this.jsapiTicketStore.get();
                if(at_forupdate == null || (long)at_forupdate.getExpires() < (System.currentTimeMillis() - at_forupdate.getLastCacheTimeMillis()) / 1000L) {
                    this.reflushJsapiTicket();
                }
            }
        }

        return this.jsapiTicketStore.get().getTicket();
    }

但jsapiTicketStore还是为null......依然是空指针

1.r.62-SNAPSHOT

找不到这个版本的包啊....

快照库 http://nutzam.com/core/basic/maven.html

setting.xml配置

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
            http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <localRepository>E:\Dev\apache-maven-3.5.0\repository</localRepository>
    <interactiveMode>true</interactiveMode>

	</mirror>	
  </mirrors>
</settings>

maven坐标:

  <dependency>
            <groupId>org.nutz</groupId>
            <artifactId>nutzwx</artifactId>
            <version>1.r.62-SNAPSHOT</version>     //报错
        </dependency>

找不到包呢....

挖槽......我加上这些配置就ok了

真是什么技术不懂原理不全面了解都会出问题...

感谢wendal,让程序员更加美好.（〜^㉨^)〜
