解决方法：Bean的生成方法上添加注解@RefreshScope(也可添加到配置类上),关联的配置类也需添加
范例如下：
@Configuration
@EnableAutoConfiguration
public class DataSourceConfig {
@Bean
@RefreshScope
@ConfigurationProperties(prefix = "jdbc")
public DruidDataSource dataSource() {
return new DruidDataSource();
}
}
由于sessionFactory也调用了dataSource,所以该bean也需添加@RefreshScope
@Configuration
public class MybatisConfig {
@Bean("sqlSessionFactory")
@RefreshScope
public MybatisSqlSessionFactoryBean sqlSessionFactory(MybatisConfiguration mybatisConfiguration,
DataSource dataSource,
GlobalConfiguration globalConfig) throws Exception {
MybatisSqlSessionFactoryBean sqlSessionFactory = new MybatisSqlSessionFactoryBean();
sqlSessionFactory.setDataSource(dataSource);
ResourcePatternResolver resourcePatternResolver = new PathMatchingResourcePatternResolver();
sqlSessionFactory.setMapperLocations(resourcePatternResolver.getResources(MAPPER_PATH));
sqlSessionFactory.setTypeAliasesPackage(MODEL_PACKAGE);
sqlSessionFactory.setConfiguration(mybatisConfiguration);
sqlSessionFactory.setPlugins(new Interceptor[]{
new PaginationInterceptor(),
new PerformanceInterceptor(),
new OptimisticLockerInterceptor(),
createPageInterceptor()
});
sqlSessionFactory.setGlobalConfig(globalConfig);
return sqlSessionFactory;
}
}
回归看RefreshScope作用：
被该方式注解的所有类可以在运行时被刷新，及所有使用到这些类的component将在下一个方法调用中获得新的实例，完全初始化并注入所有依赖项。该注解一般用于静态文件配置类中，该注解具体的官方地址：http://springcloud.cn/view/251
