VerifierMappingExceptions with Spring Boot 1.3.1当使用Spring Da



我使用Spring引导启动程序父级，让Spring管理我项目的所有依赖项，并使用Spring Data Cassandra和Spring Data JPA

Spring启动程序的父版本是1.2.8.RELEASE.最近我将版本更新为1.3.1.RELEASE，并开始面临Spring Data Cassandra 的奇怪问题

Cassandra entities must have the @Table, @Persistent or @PrimaryKeyClass Annotation

它说我必须用@Table等注释实体，但这些实体是Spring数据JPASpring数据的实体Cassandra i用@Table等进行了注释

起始类别：

@SpringBootApplication
@EnableJpaRepositories( repositoryFactoryBeanClass =    GenericRepositoryFactoryBean.class )
@EntityScan("com.sarvint.domain")
@Import(CassandraConfig.class)
public class Application {
public static void main( String[] args ) throws Exception
{
    SpringApplication.run(Application.class, args);
}

}

春季数据JPA配置：

@Configuration
@ComponentScan( basePackages = "com.sarvint" )
@PropertySource( value = { "classpath:application.properties" } )
public class AppConfig extends WebMvcConfigurerAdapter {
@Autowired
private Environment environment;
                                                                                                                                                                                                                                            @Override
public void configureDefaultServletHandling( DefaultServletHandlerConfigurer configurer )
{
    configurer.enable();
}
@Bean
public DataSource dataSource()
{
    HikariConfig config = new HikariConfig();
    int poolSize = 20;
    config.setMaximumPoolSize(poolSize);
    config.setDataSourceClassName(environment.getRequiredProperty("spring.datasource.driver-class-name"));
    config.addDataSourceProperty("url", environment.getRequiredProperty("spring.datasource.url"));
    config.addDataSourceProperty("user", environment.getRequiredProperty("spring.datasource.username"));
    config.addDataSourceProperty("password", environment.getRequiredProperty("spring.datasource.password"));
    return new HikariDataSource(config);
}

Spring Data JPA实体：

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table( name = "user" )
public class User implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue( strategy = GenerationType.IDENTITY )
@Column( name = "u_id" )
private Integer userId;
@Column( name = "u_first_name" )
private String firstName;
@Column( name = "u_last_name" )
private String lastName;
}

现在进入Spring Data Cassandra配置：

    package com.sarvint.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.data.cassandra.config.CassandraClusterFactoryBean;
import org.springframework.data.cassandra.config.java.AbstractCassandraConfiguration;
import org.springframework.data.cassandra.mapping.BasicCassandraMappingContext;
import org.springframework.data.cassandra.mapping.CassandraMappingContext;
import org.springframework.data.cassandra.repository.config.EnableCassandraRepositories;
@Configuration
@PropertySource(value = { "classpath:cassandra.properties" })
@EnableCassandraRepositories(basePackages="com.sarvint.cassandra.domain")
public class CassandraConfig extends AbstractCassandraConfiguration {
    private static final Logger LOG = LoggerFactory.getLogger(CassandraConfig.class);

    @Autowired
    private Environment environment;
    @Bean
    public CassandraClusterFactoryBean cluster() {
        LOG.info("INSIDE cluster()");
        CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
        cluster.setContactPoints(environment.getProperty("cassandra.contactpoints"));
        cluster.setPort(Integer.parseInt(environment.getProperty("cassandra.port")));
        return cluster;
    }
    @Override
    protected String getKeyspaceName() {
        LOG.info("INSIDE getting keyspace name");
        return environment.getProperty("cassandra.keyspace");
    }
    @Bean
    public CassandraMappingContext cassandraMapping() throws ClassNotFoundException {
        LOG.info("INSIDE cassandra mapping");
        return new BasicCassandraMappingContext();
    }
}

Spring Cassandra实体：

import org.springframework.cassandra.core.PrimaryKeyType;
import org.springframework.data.cassandra.mapping.Column;
import org.springframework.data.cassandra.mapping.PrimaryKeyColumn;
import org.springframework.data.cassandra.mapping.Table;
@Table( value = "biometric_param" )
public class BiometricParam {
    @PrimaryKeyColumn(name="user_id",ordinal=0,type=PrimaryKeyType.PARTITIONED)
    private Integer userId;
    @PrimaryKeyColumn(name="workout_uuid",ordinal=1,type=PrimaryKeyType.PARTITIONED)
    private String workoutUUID;
    @PrimaryKeyColumn(name="bio_param_key",ordinal=2,type=PrimaryKeyType.CLUSTERED)
    private String bioParamKey;
    @Column(value="bio_param_val")
    private Float bioParamValue;
}

Cassandra属性

cassandra.contactpoints=127.0.0.1
cassandra.port=9042
cassandra.keyspace=test

谢谢你的帮助！

问题出在哪里

这是Spring Data Cassandra中的一个错误。类路径上有多个Spring Data模块。在这种情况下，SpringData试图弄清楚特定Repository属于哪个模块。Spring Data Cassandra错过了识别您的JPA实体User不属于Cassandra的位置，因此Spring Data Cas桑德拉试图为您的UserRepository创建一个Repository实例。

如果启用DEBUG日志记录，您将看到一些DEBUG日志消息，表示Spring Data正在进入严格的配置模式。

为什么现在出现这个bug而不是早期的Spring Boot版本

Spring Boot 1.3.0引入了Spring Data Cassandra存储库的自动配置。由于这一更改，Spring Boot对Spring Data Cassandra存储库执行扫描，就像您仅使用@EnableCassandraRepositories配置它一样。

只有使用多个Spring Data模块的默认EnableCassandraRepositories的组合才能揭示此错误。

那么，现在怎么办

在application.properties中设置spring.data.cassandra.repositories.enabled=false以禁用自动配置，因为您自己使用的是@EnableCassandraRepositories(basePackages="com.sarvint.cassandra.domain")。

我在这里创建了一个错误报告，所以如果你愿意，你可以跟踪进度。

尝试升级到HikariCP 2.4.4。它包含此修复程序：

issue 495: implemented iterator() method on custom FastList to support Tomcat memory leak detection.
