Question

我正在使用Springboot版本2.1.2和MSSQL Server作为数据源。当我只使用一个数据源时，envers没问题。审核工作正常。但是，当一个项目需要两个数据源时，envers无法配合。我只需要审核第一个数据源。

这是配置：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    basePackages = { "com.sample.app.repository", "com.sample.app.security.repository" },
    repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class
)
public class MainDbConfig {
    @Bean
    @Primary
    @ConfigurationProperties("spring.datasource")
    public DataSourceProperties appDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @Primary
    @ConfigurationProperties("spring.datasource.hikari")
    public HikariDataSource appDataSource() {
        return mainDataSourceProperties().initializeDataSourceBuilder().type(HikariDataSource.class).build();
    }

    @Primary
    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(
        EntityManagerFactoryBuilder builder, @Qualifier("appDataSource") DataSource dataSource) {
        return builder
            .dataSource(dataSource)
            .packages("com.sample.app.model", "com.sample.app.security.model", "com.sample.app.audit")
            .persistenceUnit("app")
            .build();
    }

    @Primary
    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager(
        @Qualifier("entityManagerFactory") EntityManagerFactory entityManagerFactory) {
        return new JpaTransactionManager(entityManagerFactory);
    }
}

和

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    entityManagerFactoryRef = "otherEntityManagerFactory",
    transactionManagerRef = "otherTransactionManager",
    basePackages = {"com.sample.other.repository"}
)
public class OtherDbConfig {
    @Bean
    @ConfigurationProperties(prefix = "other.datasource")
    public DataSourceProperties otherDataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @ConfigurationProperties("other.datasource.hikari")
    public HikariDataSource otherDataSource() {
        return otherDataSourceProperties().initializeDataSourceBuilder().type(HikariDataSource.class).build();
    }

    @Bean(name = "otherEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(
        EntityManagerFactoryBuilder builder, @Qualifier("otherDataSource") DataSource dataSource) {
        return builder
            .dataSource(dataSource)
            .packages("com.sample.other.model")
            .persistenceUnit("other")
            .build();
    }

    @Primary
    @Bean(name = "otherTransactionManager")
    public PlatformTransactionManager transactionManager(
        @Qualifier("otherEntityManagerFactory") EntityManagerFactory entityManagerFactory) {
        return new JpaTransactionManager(entityManagerFactory);
    }
}

在访问审计之前，一切都很好，可以访问这两个数据源。我创建了一个自定义侦听器：

public class AuditRevisionListener implements RevisionListener {
     @Value("${jwt.header:Authorization}")
     private String tokenHeader;
     @Autowired
     private TokenUtil jwtTokenUtil;

     @Override
     public void newRevision(Object revisionEntity) {
         AuditRevisionEntity auditRevisionEntity = (AuditRevisionEntity) revisionEntity;
         HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
         String username =  jwtTokenUtil.getUsernameFromToken(request.getHeader("X-Auth-Token"));
         auditRevisionEntity.setUsername(username);
     }
 }

tokenHeader不会被填充，TokenUtil不会被初始化。当我使用一个数据源时，一切都很好。

任何帮助将不胜感激。
