项目启动时报错，一般都是由于配置问题，常见情况有以下几种，请参考解决。

ES 配置问题

启动时报错：

  1. org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'weCallBackController': Unsatisfied dependency expressed through field 'weEventHandle'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'weEventHandle': Unsatisfied dependency expressed through field 'weCallBackEventFactoryMap'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'weEventChangeContactImpl': Unsatisfied dependency expressed through field 'weStrategyBeanFactory'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'weStrategyBeanFactory' defined in file [D:\pactera\link-wechat\linkwe-wecom\target\classes\com\linkwechat\wecom\factory\WeStrategyBeanFactory.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'msg_audit_approved': Unsatisfied dependency expressed through field 'weChatContactMappingService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'weChatContactMappingServiceImpl': Unsatisfied dependency expressed through field 'weConversationArchiveService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'weConversationArchiveServiceImpl': Unsatisfied dependency expressed through field 'elasticSearch'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'elasticSearch': Unsatisfied dependency expressed through field 'restHighLevelClient'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'restHighLevelClient' defined in class path resource [com/linkwechat/common/config/ElasticSearchConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.elasticsearch.client.RestHighLevelClient]: Factory method 'restHighLevelClient' threw exception; nested exception is java.lang.ArrayIndexOutOfBoundsException: 1

这种是由于项目中运用到了 ES，那项目运行必须需要 ES 吗？非必需。
**
如果不需要使用，只需要注释掉相关 ES 配置信息即可：

1、注释掉 pom.xml 中关于 ES 的配置；
2、注释掉 ElasticSearchConfig.java 类，这个配置读取了配置文件中的 ES 配置信息。

如果可以使用，需要在 application.yml 文件中，增加端口号：

  1. # elasticsearch 配置
  2. elasticsearch:
  3.   schema: http
  4.   # 这里记得增加端口号
  5.   address: 127.0.0.1:端口号
  6.   userName: ""
  7.   password: ""
  8.   connectTimeout: 10000
  9.   socketTimeout: 10000
  10.   connectionRequestTimeout: 10000
  11.   maxConnectNum: 100
  12.   maxConnectPerRoute: 100

这是由于在 Windows 环境下加载系统 Dll 文件的问题，可以尝试使用 System.load 方法加载 dll 文件：

  1. static {
  2.     if (isWindows()) {
  3.         String path = System.getProperties().getProperty("user.dir");
  4.         System.load(path + File.separator + "libcrypto-1_1-x64.dll");
  5.         System.load(path + File.separator + "libcurl-x64.dll");
  6.         System.load(path + File.separator + "libssl-1_1-x64.dll");
  7.         System.load(path + File.separator + "WeWorkFinanceSdk.dll");
  8.     } else {
  9.         System.load("/data/jenkins_home/app/projects/libWeWorkFinanceSdk_Java.so");
  10.     }
  11. }
