Spring Boot：作为Java应用程序运行，但classpath包含spring-web

Question

I've successfully managed to create a Spring boot application that runs as a Java application as follows:

@SpringBootApplication
public class Application {

public static void main(String[] args) throws Exception {
    SpringApplication springApplication = new SpringApplication();
    springApplication.setWebEnvironment(false);
    springApplication.run(Application.class, args);
}

The problem is that my application requires the spring-web module as it is a client to a REST service.

Once I add the spring-web module I get an error:

Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

How can I get it to run as a Java application with spring-web on the classpath

Answer 1

I have "same setup" as you - command line spring boot app that uses RestTemplate from spring-web and everything works well. Maybe it is just that I use "full" spring web starter.

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

(and just slightly different main but it shouldn't be a difference)

    SpringApplication app = new SpringApplication(MyApplication.class);
    app.setWebEnvironment(false);
    app.run(args);
