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);
}
}`
