激活 6 个应用程序 + Weblogic 12 = "ServletContext must not be null"

Question

我正在尝试将 Activiti 6 activiti-app.war 文件部署到 Weblogic 12，但在尝试访问登录页面时出现以下异常：

java.lang.IllegalArgumentException: ServletContext must not be null

这是我的 weblogic.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.5/weblogic-web-app.xsd">

        </wls:prefer-application-packages>
    </wls:container-descriptor>
</wls:weblogic-web-app>

知道如何解决这个问题

Answer 1

在 WebConfigurer Servlet Context Listener 的 DelegatingFilterProxy 构造函数中提供 webservletcontext 对象对我有用。

initSpringSecurity 方法中现有的代码片段如下

FilterRegistration.Dynamic springSecurityFilter = servletContext.addFilter("springSecurityFilterChain", new DelegatingFilterProxy());

像下面这样修改 addFilter 调用后它起作用了：

WebApplicationContext webAppContext = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);

FilterRegistration.Dynamic springSecurityFilter = servletContext.addFilter("springSecurityFilterChain", new DelegatingFilterProxy("springSecurityFilterChain",webAppContext));

Answer 2

如果您遇到错误

No WebApplicationContext found: no ContextLoaderListener registered?

调用方法 WebApplicationContextUtils.getRequiredWebApplicationContext 时，尝试像这样实例化 WebContext：

AnnotationConfigWebApplicationContext webAppContext = new AnnotationConfigWebApplicationContext();
        webAppContext.register(ResourceWebConfig.class);

其中 ResourceWebConfig class 是：

@Configuration
@EnableWebMvc
public class ResourceWebConfig extends WebMvcConfigurerAdapter {
}

激活 6 个应用程序 + Weblogic 12 = "ServletContext must not be null"

Activiti 6 App + Weblogic 12 = "ServletContext must not be null"
