我正在使用 Spring Boot 和 JSP 來學習 Spring Security 中的一些快速教程，但我的控制器映射并index.jsp不起作用。似乎找不到JSP頁面。這是我的配置和項目結構：springsecurity-for-reactive-apps [boot] - Project folder - src/main/java - com.springsecurity - SpringsecurityForReactiveAppsApplication.java - com.springsecurity.config - ApplicationConfig.java - SecurityWebApplicationInitializer.java - SpringMvcWebApplicationInitializer.java - SpringSecurityConfig.java - WebApplicationConfig.java - src - main - webapp - WEB-INF - view - home.jsp - index.jspcom.springsecurity包包含@SpringBootApplicationpublic class SpringsecurityForReactiveAppsApplication { public static void main(String[] args) { SpringApplication.run(SpringsecurityForReactiveAppsApplication.class, args); }}com.springsecurity.config 包包含以下類@Configuration public class ApplicationConfig { @Value("${spring.datasource.driver-class-name}") private String DB_DRIVER; @Value("${spring.datasource.password}") private String DB_PASSWORD; @Value("${spring.datasource.url}") private String DB_URL; @Value("${spring.datasource.username}") private String DB_USERNAME; @Autowired private Environment env; @Bean public DataSource getDataSource() { DriverManagerDataSource dataSource = new DriverManagerDataSource(); dataSource.setDriverClassName(DB_DRIVER); dataSource.setUrl(DB_URL); dataSource.setUsername(DB_USERNAME); dataSource.setPassword(DB_PASSWORD); return dataSource; } }

在你的 pom.xml 中刪除
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp.jstl</groupId>
<artifactId>javax.servlet.jsp.jstl-api</artifactId>
<version>1.2.1</version>
</dependency>
并添加這些依賴項
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
據我所知，tomcat-embed-jasper需要在啟動時呈現jsp頁面。

1.viewResolver.setPrefix("/WEB-INF/views/"); 視圖->視圖
2.spring可以實現ErrorController
@Controller
public class ViewController implements ErrorController {
@GetMapping("/home")
public String home(Model model) {
System.out.println("___________home()___________________");
return "home";
}
@GetMapping("/error")
public String error(Model model) {
System.out.println("___________ERROR-<<error___________________");
return "home";
}
@Override
public String getErrorPath() {
return "/error";
}
}
