java - Spring Boot 显示对索引的 http 请求，但不显示任何其他映射

Question

Spring Boot 显示对索引路径的 HTTP 请求，但不显示任何其他映射。

我创建了一个在 localhost:8060 上运行的 spring boot 应用程序。问题是，当我在浏览器上运行 localhost:8060 时，它可以正常工作，但是当我运行任何其他请求时，它会显示“出现意外错误(type=Forbidden，status=403)”。 拒绝访问'。在日志中它说它找到了正确的方法，即它映射正确但仍然抛出这个错误。

问候语.java

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Main application to launch spring boot.
 */
@RestController
public class Greetings {

    /**
     * Main application to launch spring boot.
     */
    @RequestMapping("/")
    public String index() {
        return "Greetings from Spring Boot!";
    }

    @RequestMapping("/testing123")
    public String indextest() {
        return "Testing";
    }
}

服务器应用

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.annotation.EnableAsync;

/**
 * Main application to launch spring boot.
 */
@SpringBootApplication
@EnableAutoConfiguration
@EnableAsync
public class ServerApplication {

    private static Logger logger = LoggerFactory.getLogger(ServerApplication.class);

    /**
     * Start the Spring Boot application.
     *
     * @param args command line arguments
     */
    public static void main(String[] args) {
        ApplicationContext context = SpringApplication.run(ServerApplication.class, args);
        logger.info("Sample Application started with context {}", context.getDisplayName());
    }
}

应用程序属性

# Initialize feature service.
# This flag should be set ONLY in environments where ss-backend isn't running - normally - ss-backend is set as the
# leader so that it can control (via UI) setting any and all features.
feature.service.is.leader=true

logging.level.org.springframework.web: TRACE


security.ignored=/**
security.basic.enable: false

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

所以它会显示“来自 Spring Boot 的问候!”当我转到 localhost:8060 但在 localhost:8060/testing123 上抛出错误

Answer 1

因为你主类ServerApplication在另一个包中，它是 spring boot 应用程序的基础包。

但是 Controller Greetings在不同的包中，不是主类的子包，默认情况下，spring boot 应用程序加载所有用 sub packages 中的任何构造型注释注释的类基础包的 spring bean 入ApplicationContext

使用 @ComponentScan在 Main类

@SpringBootApplication
@EnableAutoConfiguration
@EnableAsync
@ComponentScan({"com.vmware.skyscraper", "com.skyscraper.vdisizer"})
public class ServerApplication {

private static Logger logger = LoggerFactory.getLogger(ServerApplication.class);

/**
 * Start the Spring Boot application.
 *
 * @param args command line arguments
 */
public static void main(String[] args) {
    ApplicationContext context = SpringApplication.run(ServerApplication.class, args);
    logger.info("Sample Application started with context {}", context.getDisplayName());
  }
}
