無法訪問我的Spring Boot應用程序頁面

Question

我創建了Spring Boot應用程序，我不知道為什么，但是我無法訪問我的視圖，我認為問題可能出在Spring Boot解析器上。

//我的控制器

@Controller
public class PageController {

@RequestMapping(value = "/api/v1/dataSource/creation", method = RequestMethod.GET)
public String homePage() {
    System.out.println("checked here");
    return "home";
}
}

//配置

@Configuration
@EnableWebSecurity
public class DataIntegratorSecurityConfiguration extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.authorizeRequests().antMatchers("/").permitAll();
    http.csrf().disable();
    http.headers().frameOptions().disable();
}
}

@Configuration
public class DataIntegratorConfiguration {

@Bean(name = "DataSourceMetadataCache")
public ConcurrentHashMap<String, DataSourceMetadata> cache() {
    return new ConcurrentHashMap<String, DataSourceMetadata>();
}

@Bean(name = "jmsRequestResponseCache")
public ConcurrentHashMap<String, JMSExchange> jmsReqResCache() {
    return new ConcurrentHashMap<String, JMSExchange>();
}
}

錯誤：

白標錯誤頁面

此應用程序沒有針對/ error的顯式映射，因此您將其視為后備。

Answer 1

您尚未添加任何模板引擎。 添加spring-boot-thymeleaf-starter依賴項，Spring Boot將為您配置視圖解析器：

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