在Spring Boot中使用多个分派器Servlet / Web上下文
问题内容：
我创建了一个带有父上下文（服务）和子上下文（spring-webmvc控制器）的spring boot应用程序：
@Configuration
public class MainApiApplication {
public static void main(String[] args) {
new SpringApplicationBuilder()
.parent(Services.class)
.child(ApiOne.class, MainApiApplication.class)
.run(args);
}
@Bean
public EmbeddedServletContainerFactory servletContainer() {
return new TomcatEmbeddedServletContainerFactory();
}
}
现在，我想为我的ApiTwo.class配置添加另一个客户端上下文（和DispatcherServlet）。我认为我必须做两件事：
- 将servletContainer（因此MainApiApplication.class配置）移出子上下文，然后
- 添加路径映射/ one /-> ApiOne.class和/ two / ApiTwo.class
spring靴子是怎么做的？
问题答案：
正如@ josh-
ghiloni所说，您需要为ServletRegistrationBean要创建的每个隔离的Web上下文注册一个。您需要从xml或java
config类创建应用程序上下文。您可以使用@Import和@ComponentScan注释将共享服务添加到父上下文。这是一个例子：
import org.springframework.boot.SpringApplication;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.context.support.XmlWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
//@ComponentScan({"..."})
//@Import({})
public class Starter {
public static void main(String[] args) throws Exception {
SpringApplication.run(Starter.class, args);
}
@Bean
public ServletRegistrationBean apiV1() {
DispatcherServlet dispatcherServlet = new DispatcherServlet();
XmlWebApplicationContext applicationContext = new XmlWebApplicationContext();
applicationContext.setConfigLocation("classpath:/META-INF/spring/webmvc-context.xml");
dispatcherServlet.setApplicationContext(applicationContext);
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(dispatcherServlet, "/api/1/*");
servletRegistrationBean.setName("api-v1");
return servletRegistrationBean;
}
@Bean
public ServletRegistrationBean apiV2() {
DispatcherServlet dispatcherServlet = new DispatcherServlet();
AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
applicationContext.register(ResourceConfig.class);
dispatcherServlet.setApplicationContext(applicationContext);
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(dispatcherServlet, "/api/2/*");
servletRegistrationBean.setName("api-v2");
return servletRegistrationBean;
}
}
