Question

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

我遵循了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);

}

主要课程：

@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：

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

错误如下：

Answer 1

您需要将@SpringBootApplication添加到主类。

@EnableGemfireRepositories
@SpringBootApplication
public class Application implements CommandLineRunner {

并在你的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

要简化 Spring Boot 应用程序中的Pivotal GemFire配置，您可以考虑使用（以）开头的 Spring Boot for Pivotal GemFire （SBDG）project。

SBDG基于 Pivotal GemFire的Spring数据 （SDG）以及其他Spring项目（显然是 Spring Boot ）以及 Pivotal GemFire的春季会议 （SSDG； here）。在开发Pivotal GemFire应用程序时，它将应用 Spring Boot 的所有概念（例如，使用自动配置的自以为是的“使用配置进行约定的惯例”等）。通常使用Spring，尤其是 Spring Boot 。

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

使用SBDG也有许多其他好处。

令人回味的食物。
