NullPointerException in transactionAdviser (Spring boot application)
我在开发 Spring 引导应用程序时遇到了一个奇怪的异常。我浏览了很多，但找不到太多可以挽救的东西。这是我拥有的：

该项目 运行 没有错误并且工作正常。我没有对代码进行任何更改，然后在一瞬间我得到了这个异常。
这是我的 JpaConfig：

提前致谢！
我看到您在 pom.xml 中依赖于快照版本控制。这意味着您将提取任何可能不完全没有错误的最新版本。如果您查看错误消息，您会看到
spring-boot-1.4.0.BUILD-20160727.140415-585.jar:1.4.0.BUILD-SNAPSHOT
这是今天构建的版本，可能不完全稳定。而是更改您的 pom 以使用当前的一般可用性版本以获得稳定性

该项目 运行 没有错误并且工作正常。我没有对代码进行任何更改，然后在一瞬间我得到了这个异常。
这是我的 JpaConfig：
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories({
"com.webstore.common.repository.jpa",
"com.webstore.web.repository.jpa"
})
public class JpaConfig implements TransactionManagementConfigurer {
@Value("${dataSource.url}")
private String datasourceUrl;
@Value("${dataSource.username}")
private String datasourceUsername;
@Value("${dataSource.password}")
private String datasourcePassword;
@Value("${dataSource.driverClassName}")
private String datasourceDriverClassName;
@Value("${hibernate.dialect}")
private String hibernateDialect;
@Value("${hibernate.hbm2ddl.auto}")
private String hibernateHbm2ddlAuto;
@Bean
public DataSource configureDataSource() {
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setDriverClassName(datasourceDriverClassName);
hikariConfig.setJdbcUrl(datasourceUrl);
hikariConfig.setUsername(datasourceUsername);
hikariConfig.setPassword(datasourcePassword);
return new HikariDataSource(hikariConfig);
}
@Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean configureEntityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(configureDataSource());
entityManagerFactoryBean.setPackagesToScan("com.webstore");
entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
Properties jpaProperties = new Properties();
jpaProperties.put(org.hibernate.cfg.Environment.DIALECT, hibernateDialect);
jpaProperties.put(org.hibernate.cfg.Environment.HBM2DDL_AUTO, hibernateHbm2ddlAuto);
entityManagerFactoryBean.setJpaProperties(jpaProperties);
return entityManagerFactoryBean;
}
@Bean
@Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new JpaTransactionManager();
}
}

提前致谢！
我看到您在 pom.xml 中依赖于快照版本控制。这意味着您将提取任何可能不完全没有错误的最新版本。如果您查看错误消息，您会看到
spring-boot-1.4.0.BUILD-20160727.140415-585.jar:1.4.0.BUILD-SNAPSHOT
这是今天构建的版本，可能不完全稳定。而是更改您的 pom 以使用当前的一般可用性版本以获得稳定性
