通过DataSource bean手动配置数据库后到处都是LazyIntializeException

问题描述 投票：0回答：1

我将视图中打开会话的所有项目设置为 true，现在我需要添加一个新的数据库来项目，它导致手动配置我的旧数据源，如下所示（之前是在 application.properties 上配置的）：

@DependsOn("assinanteContext")
@Configuration
@EnableJpaRepositories(
        basePackages = "org.crm", // Adjusted package for primary repositories
        entityManagerFactoryRef = "mainEntityManagerFactory",
        transactionManagerRef = "mainTransactionManager",
        excludeFilters = @ComponentScan.Filter(
                type = FilterType.ASSIGNABLE_TYPE, classes = {
                AssinanteRepository.class
        }
        )
)
public class DataSourceConfig {

    @Autowired
    private AssinanteContext assinanteContext;

    @Value("${app.assinante-cnpj}")
    private String cnpj;

    @Bean
    public DataSource dataSource() {
        HikariConfig hikariConfig = new HikariConfig();
        hikariConfig.setJdbcUrl(assinanteContext.dbURL);
        hikariConfig.setUsername(assinanteContext.dbUser);
        hikariConfig.setPassword(assinanteContext.dbPass);

        hikariConfig.setConnectionTestQuery("SELECT 1");
        hikariConfig.setValidationTimeout(3000);
        hikariConfig.setIdleTimeout(60000);
        hikariConfig.setMaxLifetime(1800000);
        hikariConfig.setMinimumIdle(5);
        hikariConfig.setMaximumPoolSize(20);

        return new HikariDataSource(hikariConfig);
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean mainEntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setDataSource(dataSource());
        factory.setPackagesToScan("org.crm"); // Main packages to scan
        factory.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
        Properties properties = new Properties();
        properties.put("hibernate.physical_naming_strategy", "org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy");
        properties.put("hibernate.implicit_naming_strategy", "org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy");
        factory.setJpaProperties(properties);
        return factory;
    }

    @Bean
    public JpaTransactionManager mainTransactionManager(EntityManagerFactory mainEntityManagerFactory) {
        return new JpaTransactionManager(mainEntityManagerFactory);
    }
}

问题是我在整个应用程序上遇到了lazyInitializationException，

即使有警告

WARN 13764 --- [  restartedMain] JpaBaseConfiguration$JpaWebConfiguration : spring.jpa.open-in-view is enabled by default.

我知道我可以使用

@Transactional
Hibernate.initialize
EAGER
但是在手动配置
Datasource
之前所有项目都运行良好，不值得重新配置100个相关实体的文件来解决这个问题，我真的认为OSIV被破坏了

添加了有关 

mainEntityManagerFactory()
的 bean 配置：

@Configuration
public class OsivConfig {
    @Bean
    public OpenSessionInViewFilter openSessionInViewFilter() {
        OpenSessionInViewFilter filter = new OpenSessionInViewFilter();
        filter.setSessionFactoryBeanName("mainEntityManagerFactory");
        return filter;
    }
}
