Question

首先，我不知道Maven，Tomcat和Java。

我有一个.war文件，其中包含一个网页和一台安装在Mac（Yosemite）中的Tomcat 8服务器。位于/Library/Tomcat/webapps/wm-admin-ui.war。我还安装了Maven（v3）并配置了tomcat用户。

我需要在Tomcat服务器中运行.war，它显然是由一些Maven插件部署的。我认为这是因为在META-INF上有一个maven目录，而且通常的部署根本不起作用。见下面的图片作为参考。

事情是，

如何在tomcat 8中安装maven插件？（我已经检查了谷歌）
是＆＃34;部署＆＃34; ＆＃34;运行＆＃34;？

这是通过错误的代码：

private String getSwaggerBasePath() {
    InputStream is = getClass().getResourceAsStream("/swagger.properties");
    Properties properties = new Properties();
    try {
        properties.load(is);
        is.close();
    } catch (IOException e) {
        LOGGER.error("Failed to handle stream for swagger.properties file ", e);
    }

    String context = properties.getProperty("swagger.base_path", "");

    return (StringUtils.isEmpty(context) ? "" : context) + "/wm-admin-ui/rest";
}

Answer 1

似乎带有方法com.toro.wm.configurations.WmWebApplicationInitializer的类getSwaggerBasePath在加载某些属性文件时出现问题。

在此课程WmWebApplicationInitializer.java:86中查看此行。似乎你没有部署关键文件，当应用程序初始化上下文时，它需要该文件。

第二个问题是您需要将所有属性放在路径WEB-INF/classes中。

现在一切都应该有效。

运行（部署？）a＆＃34; maven＆＃34; .war在TOMCAT 8
