Question

我无法通过以下配置加载home.html。控制器始终重定向到src / main / resources / templates / error.html。可能是什么问题？我还在我的pom中包含了thymleaf依赖性，并提出了一个这样的建议。配置类：

@SpringBootApplication
@ComponentScan("com.sg.repository.")
public class SgmembersApplication {


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


    @Bean
    public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
        return hemf.getSessionFactory();
    }
}

的src /主/资源/模板/ home.html做为

 <!DOCTYPE HTML>
<html>
  <head>  
    <title>Members</title> 
     <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
  </head>
  <body>
   <label> This is home page</label>    
  </body>
</html>

控制器：

@Controller
public class MainController {


     @RequestMapping("/")
     public String getHomePage() {
         return "home";
     }

     @RequestMapping("/error")
     public String getErrorPage() {
         return "error";
     }

application.properties

    # Database
spring.datasource.driverClassName: com.mysql.jdbc.Driver
spring.datasource.url: jdbc:mysql://localhost:3306/sg
spring.datasource.username: 
spring.datasource.password: 

# Hibernate

spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

Answer 1

审核了您的代码。更改您的组件扫描以扫描每个相关包，或仅扫描所有内容，例如@ComponentScan("com.sg.")

然后您的映射将被正确设置：

s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/]}" onto public java.lang.String com.sg.members.controller.MainController.getHomePage()

其他一些提示：Thymeleaf希望再次关闭任何HTML-Tag。你的home.html会抛出一些错误，但只需关闭标签就可以轻松修复。（例如<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"/>。最后注意“/”。）

输入，img和其他所有字段也一样。
