addInterceptor
3个地方
- XML 解析的
- SqlSessionFactoryBean: 生成 SqlSession 的 FactoryBean
- PageHelperAutoConfiguration: 分页助手的自动配置
SqlSessionFactoryBean
发现现在都没有将他作为一个 FactoryBean 使用了
getObject 调用了 afterPropertiesSet 生成 SqlSessionFactory 实例
原来 onApplicationEvent 的作用是啥?
@Override
public SqlSessionFactory getObject() throws Exception {
// 没有实例则调用 afterPropertiesSet 生成
if (this.sqlSessionFactory == null) {
afterPropertiesSet();
}
// 返回实例
return this.sqlSessionFactory;
}
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
if (failFast) {
// fail-fast -> check all statements are completed
// ? 啥
this.sqlSessionFactory.getConfiguration().getMappedStatementNames();
}
}
@Override
public void afterPropertiesSet() throws Exception {
// 数据源、sqlSessionFactoryBuilder 必须已存在
notNull(dataSource, "Property 'dataSource' is required");
notNull(sqlSessionFactoryBuilder, "Property 'sqlSessionFactoryBuilder' is required");
// 要么存在配置实例, 要么存在配置文件路径
state((configuration == null && configLocation == null) || !(configuration != null && configLocation != null),
"Property 'configuration' and 'configLocation' can not specified with together");
this.sqlSessionFactory = buildSqlSessionFactory();
}
