项目配置

启动类不能放在文件夹下，不然会找不到页面
application.properties下加上

#设置端口号
server.port=8011
#配置视图解析器的前缀
spring.mvc.view.prefix=/WEB-INF/jsp/
#配置视图解析器的后缀
spring.mvc.view.suffix=.jsp

启动类写成如下形式

@SpringBootApplication
public class ShowCalApplication extends SpringBootServletInitializer{

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(ShowCalApplication.class);
    }
}

启动

不要用main方法启动，会报页面找不到，用spring-boot:run方法启动

运行

1. 扔到tomcat中运行
2. 直接java -jar启动

java -jar weibo-api-1.0.war
