spring boot 複数DBに接続時interceptor無効になるについて

step1

@Import({DataSourceConfiguration.class,PageInterceptor.class})

step2

@Autowired
    private PageInterceptor pageInterceptor;

step3

sqlSessionFactoryBean.setPlugins(newInterceptor[]{pageInterceptor});

step3は「sqlSessionFactoryBean.getObject()」前に書く

原因

sqlSessionFactoryBean.getObject()

public SqlSessionFactory getObject() throws Exception {
    if (this.sqlSessionFactory == null) {
      afterPropertiesSet();
    }

    return this.sqlSessionFactory;
}

public void afterPropertiesSet() throws Exception {
    notNull(dataSource, "Property 'dataSource' is required");
    notNull(sqlSessionFactoryBuilder, "Property 'sqlSessionFactoryBuilder' is required");
    state((configuration == null && configLocation == null) || !(configuration != null && configLocation != null),
              "Property 'configuration' and 'configLocation' can not specified with together");

    this.sqlSessionFactory = buildSqlSessionFactory();
  }

if (!isEmpty(this.plugins)) {
      for (Interceptor plugin : this.plugins) {
        configuration.addInterceptor(plugin);
        if (LOGGER.isDebugEnabled()) {
          LOGGER.debug("Registered plugin: '" + plugin + "'");
        }
      }
    }
