Question

我创建了我的春季启动应用程序，我不知道为什么，但我无法访问我的视图，我想可能问题是弹簧启动解析器。

//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>();
}
}

错误：

Whitelabel错误页面

此应用程序没有/ error的显式映射，因此您将此视为后备。

Fri Jun 23 12:14:45 WET 2017 出现意外错误（type = Not Found，status = 404）。找不到

Answer 1

您尚未添加任何模板引擎。添加spring-boot-thymeleaf-starter依赖项，Spring Boot将为您配置视图解析器：

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

无法访问我的Spring启动应用程序页面
