对于基于Spring Boot的应用程序,我在application.properties上配置了ssl属性,请参阅我的配置:

server.port=8443
server.ssl.key-alias=tomcat
server.ssl.key-password=123456
server.ssl.key-store=classpath:key.p12
server.ssl.key-store-provider=SunJSSE
server.ssl.key-store-type=pkcs12

我在Application.class上添加了连接,就像

@Bean
public EmbeddedServletContainerFactory tomcatEmbeddedServletContainerFactory() {
    final TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
    factory.addAdditionalTomcatConnectors(this.createConnection());
    return factory;
}

private Connector createConnection() {
    final String protocol = "org.apache.coyote.http11.Http11NioProtocol";
    final Connector connector = new Connector(protocol);

    connector.setScheme("http");
    connector.setPort(9090);
    connector.setRedirectPort(8443);
    return connector;
}

但是,当我尝试以下时

http://127.0.0.1:9090/

重定向到

https://127.0.0.1:8443/

没有执行.谁遇到过类似的问题？

Spring Boot的嵌入式tomcat非常方便,适用于开发和部署.

但是如果应该添加另一个(第三方)WAR文件(例如,GeoServer)呢？

也许以下是正常程序:

1. 安装普通的Tomcat服务器.
2. 将Spring Boot应用程序构建为WAR文件,并将其添加到Tomcat的webapps文件夹中.
3. 还要将另一个(第三方)WAR文件添加到webapps文件夹.

但如果可以进行以下配置,那就太好了.

1. 将Spring启动应用程序构建为独立的Jar,其中包括嵌入式Tomcat.
2. 部署Spring启动应用程序Jar.
3. 将另一个(第三方)WAR文件添加到嵌入式Tomcat识别的文件夹中.
4. 使用嵌入式Tomcat提供Spring引导应用程序内容和另一个WAR的内容.

怎么做到呢？

UPDATE

当spring引导应用程序由胖jar(=可执行jar)构成时,答案中的代码是不够的.修订后的内容如下:

@Bean
public EmbeddedServletContainerFactory servletContainerFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                Tomcat tomcat) {
            try {
                Context context = tomcat.addWebapp("/foo", "/path/to/foo.war");
                WebappLoader loader =
                    new WebappLoader(Thread.currentThread().getContextClassLoader());
                context.setLoader(loader);
            } catch (ServletException ex) {
                throw new IllegalStateException("Failed to add webapp", ex);
            }
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }

    };
}

由于系统类加载器无法加载胖jar中的jar文件,因此必须指定显式父类加载器.否则,附加WAR无法将库jar加载到添加了WAR的spring boot应用程序的fat jar中.

当我使用主应用程序运行应用程序时,我在consoleUnable中得到错误以启动Web服务器; 嵌套异常是org.springframework.context.ApplicationContextException:由于缺少ServletWebServerFactory bean,无法启动ServletWebServerApplicationContext.

主要应用

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Servlet初始化程序

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}

的build.gradle

    buildscript {
        ext {
            springBootVersion = '2.0.0.M4'
        }
        repositories {
            jcenter()
            mavenCentral()
            maven { url "https://repo.spring.io/snapshot" }
            maven { url "https://repo.spring.io/milestone" }
        }
        dependencies {
            classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        }
    }

    plugins {
        id "org.sonarqube" version "2.5"
    }

经过调试,问题是mvc配置类EnableWebMvcConfiguration加载太早,servlet尚未加载.

我的 Spring Boot 2 Web 应用程序运行良好，但现在我想将所有 http 请求重定向到 https。

但是 EmbeddedServletContainerFactory 和 TomcatEmbeddedServletContainerFactory 不能被导入。它说org.springframework.boot.context.embedded不存在。

我的代码如下：

@Bean
public EmbeddedServletContainerFactory servletContainer(){
    TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory(){
        @Override
        protected void postProcessContext(Context context) {
            SecurityConstraint securityConstraint = new SecurityConstraint();
            securityConstraint.setUserConstraint("CONFIDENTIAL");
            SecurityCollection collection = new SecurityCollection();
            collection.addPattern("/*");
            securityConstraint.addCollection(collection);
            context.addConstraint(securityConstraint);
        }
    };
    tomcat.addAdditionalTomcatConnectors(redirectConnector());
    return tomcat;
}

我使用gradle，构建文件是：

buildscript {
    ext {
        springBootVersion = '2.0.0.M6'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
} …
