Spring Boot 错误：由于缺少 EmbeddedServletContainerFactory bean，无法启动 EmbeddedWebApplicationContext

Question

我正在尝试使用 Spring Data GemFire 将数据放入 GemFire。

我关注了这个link

@Region("stockdata")
public class StockInfo {

    @Id 
    public String symbol;

    public String price;

    @PersistenceConstructor
    public StockInfo(String symbol, String price) {
        super();
        this.symbol = symbol;
        this.price = price;
    }

    @Override
    public String toString() {
        return "StockInfo [symbol=" + symbol + ", price=" + price + "]";
    }

    public String getSymbol() {
        return symbol;
    }
    public void setSymbol(String symbol) {
        this.symbol = symbol;
    }
    public String getPrice() {
        return price;
    }
    public void setPrice(String price) {
        this.price = price;
    }

}

StockRepository 类：

public interface StockRepository extends CrudRepository<StockInfo, String> {
    StockInfo findByName(String symbol);

}

主类：

@Configuration
@EnableGemfireRepositories
public class Application implements CommandLineRunner {

    @Bean
    CacheFactoryBean cacheFactoryBean() {
        return new CacheFactoryBean();

    }

    @Bean
    LocalRegionFactoryBean<String, StockInfo> localRegionFactory(final GemFireCache cache) {
        return new LocalRegionFactoryBean<String, StockInfo>() {

            {
                setCache(cache);
                setName("stockdata");
                setClose(false);
            }
        };
    }
    @Autowired
    StockRepository stockRepositry;
    public void run(String... arg0) throws Exception {
        StockInfo fbStock = new StockInfo("FB", "100");
        StockInfo aaplStock = new StockInfo("AAPL", "200");
        StockInfo msftStock = new StockInfo("MSFT", "300");

        System.out.println("Before linking up with Gemfire...");
        for (StockInfo stockInfo : new StockInfo[] {fbStock, aaplStock,msftStock }) {
            System.out.println("\t" + stockInfo);
        }

        stockRepositry.save(fbStock);
        stockRepositry.save(aaplStock);
        stockRepositry.save(msftStock);

        System.out.println("Lookup each Stock by name...");

        for (String symbol : new String[] { fbStock.symbol, aaplStock.symbol,msftStock.symbol }) {
            System.out.println("\t" + stockRepositry.findByName(symbol));
        }

    }

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

Pom.xml：

Answer 1

您需要将@SpringBootApplication 添加到您的主类中。

@EnableGemfireRepositories
@SpringBootApplication
public class Application implements CommandLineRunner {

在你的 pom 中添加 spring-boot-starter-web 依赖而不是 spring-web

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

Answer 2

为了在您的 Spring Boot 应用程序中简化您的 Pivotal GemFire 配置，您可以考虑使用（开始）Spring Boot for Pivotal GemFire (SBDG)project.

SBDG 建立在 Spring Data for Pivotal GemFire (SDG) 以及其他 Spring 项目（显然是 Spring Boot 以及 Pivotal GemFire 春季会议 (SSDG;here) 也是如此。它在开发 Pivotal GemFire 应用程序时应用了 Spring Boot 的所有概念（例如，使用自动配置的“约定优于配置”等）一般使用 Spring，尤其是 Spring Boot。

例如，在您的应用程序中，SBDG 会自动自动配置 SD[G] 存储库，从而无需显式声明 @EnableGemfireRepositories。

使用 SBDG 还有许多其他好处。

值得深思。
