bio1984 opened a new issue #4505: 自定义ShardingAlgorithm无法注入spring context URL: https://github.com/apache/incubator-shardingsphere/issues/4505 如标题描述，运行环境为Springboot，启动时已经通过@PostConstruct注解进行ApplicationContext的初始化，但初始化不成功 代码如下： `@Configuration public class ShardingJdbcConfig { @Autowired private DataSource dataSource; @Autowired ApplicationContext applicationContext; @PostConstruct public void init() { if (dataSource instanceof ShardingDataSource) { ShardingDataSource sds = (ShardingDataSource) dataSource; ShardingRuntimeContext shardingContext = sds.getRuntimeContext(); ShardingRule shardingRule = shardingContext.getRule(); StandardShardingStrategy strategy = (StandardShardingStrategy) shardingRule.getDefaultTableShardingStrategy(); ReflectionUtils.doWithFields(StandardShardingStrategy.class, field -> { if ("preciseShardingAlgorithm".equals(field.getName())) { field.setAccessible(true); Object o = field.get(strategy); ReflectionUtils.doWithMethods(ShardingAlgorithm.class, method -> { if ("init".equals(method.getName())) { try { method.invoke(o, applicationContext); } catch (Exception e) { e.printStackTrace(); } } }); } }); } } }` `public class ShardingAlgorithm implements PreciseShardingAlgorithm<Long> { ApplicationContext applicationContext; public void init(ApplicationContext ac) { applicationContext = ac; } @Override public String doSharding(Collection<String> availableTargetNames, PreciseShardingValue<Long> shardingValue) { TableShardingService tableShardingService = applicationContext.getBean(TableShardingService.class); } }`
