想在spring boot Application中使用两个DataSource（mysql，h2数据库）

Question

我想在spring boot app中使用两个数据源，比如某些表我想使用h2，而某些使用mysql使用jpa hibernate。 在我的application.java中我正在做的是..

 @Bean
    @Primary
    @ConfigurationProperties(prefix="datasource.primary")
    public DataSource primaryDataSource() {
        System.out.println(list+"============");
        return DataSourceBuilder.create().build();
    }

    @Bean
    @ConfigurationProperties(prefix="datasource.secondary")
    public DataSource secondaryDataSource() {
        return DataSourceBuilder.create().build();
    }


     @Bean(name = "entityManagerFactory")
        @Primary
        public LocalContainerEntityManagerFactoryBean primaryEntityManagerFactory(
                EntityManagerFactoryBuilder builder) {
            return builder
                    .dataSource(primaryDataSource())
                    .packages("com.opallios.ode.model")
                    .persistenceUnit("primary")
                    .properties(buildProperties())
                    .build();
        }


     @Bean(name = "secondaryEntityManagerFactory")
        public LocalContainerEntityManagerFactoryBean secondaryEntityManagerFactory(
                EntityManagerFactoryBuilder builder) {
            return builder
                    .dataSource(secondaryDataSource())
                    .packages("com.opallios.ode.model")
                    .persistenceUnit("secondary")
                    .properties(buildProperties())
                    .build();
        }

        private Map<String, Object> buildProperties() {
            // This is usually set by HibernateJpaAutoConfiguration
            Map<String, Object> properties = new HashMap<String, Object>();
            properties.put("hibernate.ejb.naming_strategy",
                    ImprovedNamingStrategy.class.getName());
            return properties;
        }

        @Bean
        @Autowired
        @Qualifier("secondaryEntityManagerFactory")
        public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
            JpaTransactionManager txManager = new JpaTransactionManager();
            txManager.setEntityManagerFactory(emf);
            return txManager;
        }

        @Bean
        @Autowired
        @Qualifier("entityManagerFactory")
        public PlatformTransactionManager transactionManagerr(EntityManagerFactory emf) {
            JpaTransactionManager txManager = new JpaTransactionManager();
            txManager.setEntityManagerFactory(emf);
            return txManager;
        } 


    @Bean   
    public ServletRegistrationBean h2servletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new WebServlet());
        Map<String,String> params = new HashMap<String,String>();
        params.put("webAllowOthers", h2WebAllow);
        registration.setInitParameters(params);
        registration.addUrlMappings("/console/*");
        return registration;
    }enter code here

它给予例外 org.springframework.beans.factory.BeanCreationException：创建名为＆＃39; springSecurityFilterChain

的bean时出错

我想要所有的建议，如果我需要一个简单的代码，其中可以配置mysql和h2 db并可以从db获取数据。
