考虑在配置中定义类型为"javax.servlet.ServletContext"的 bean

Question

我正在尝试将API与postgres数据库连接起来。为此，我正在使用Spring Boot。 测试api时，我不断收到错误

考虑在配置中定义类型为"javax.servlet.ServletContext"的 bean。

我知道我需要@BeanServletController，但我不知道这个豆子应该做什么。当我做了一个通用的，但后来控制台告诉我重新访问它。我不知道在这里该怎么做，堆栈溢出也无济于事。

这是我的应用程序文件：

@SpringBootApplication
@SwaggerDefinition
@EnableSwagger2
@EnableConfigurationProperties(XXXXConfiguracaoApplication.class)
public class FonumS3ApiApplication  {
public static void main(String[] args) {
SpringApplication.run(XXXXApiApplication.class, args);
}
@Bean
public Docket api() { 
return new Docket(DocumentationType.SWAGGER_2)  
.select()                                  
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any()) 
.build()
.apiInfo(apiInfo());                                           
}
private ApiInfo apiInfo() {
return new ApiInfo(
"API XXXX", 
"API XXXX para integrações entre sistemas.", 
"API V1", 
"Terms of service", 
new Contact("XXXX", "www.XXXX.com", "[e-mail]"), 
"License of XXX", "API license URL", Collections.emptyList());
}
}
} 

(注释在那里，但由于某种原因，堆栈溢出不接受它们(我的pom是

由于您已经从 Web 中排除了 Tomcat 并添加了 Tomcat 提供的范围，所以我假设您正在尝试创建战争并在外部 Tomcat 上部署，因此您必须扩展SpringBootServletInitializer并覆盖configure方法。

@SpringBootApplication
@SwaggerDefinition
@EnableSwagger2
@EnableConfigurationProperties(XXXXConfiguracaoApplication.class)
public class FonumS3ApiApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(XXXXApiApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
@Bean
public Docket api() { 
return new Docket(DocumentationType.SWAGGER_2)  
.select()                                  
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any()) 
.build()
.apiInfo(apiInfo());                                           
}
private ApiInfo apiInfo() {
return new ApiInfo(
"API XXXX", 
"API XXXX para integrações entre sistemas.", 
"API V1", 
"Terms of service", 
new Contact("XXXX", "www.XXXX.com", "[e-mail]"), 
"License of XXX", "API license URL", Collections.emptyList());
}
}
} 

或者，如果您使用嵌入式 Tomcat 运行，则不要更改主类中的任何内容并从 web 中删除exclusion并删除 Tomcat jar：

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

并移除下面的雄猫罐：

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
