国产框架Solon配置

easy-query在^1.2.6正式支持Solon适配国产框架的orm部分。

什么是Solon

Solonopen in new window Java 新的生态型应用开发框架：更快、更小、更简单。

启动快 5 ～ 10 倍；qps 高 2～ 3 倍；运行时内存节省 1/3 ~ 1/2；打包可以缩到 1/2 ~ 1/10；同时支持 jdk8, jdk11, jdk17, jdk20, graalvm native image。

新建DataSource注入

@Configuration
public class WebConfiguration {
    @Bean(name = "db1",typed=true)
    public DataSource db1DataSource(@Inject("${db1}") HikariDataSource dataSource){
        return dataSource;
    }
}

新增控制器


@Controller
@Mapping("/test")
public class TestController {
    @Mapping(value = "/hello",method = MethodType.GET)
    public String hello(){
        return "Hello World";
    }
}

Solon启动

        });
    }
}

//输入url http://localhost:8080/test/hello

//返回Hello World

easy-query查询

@Data
@Table("t_topic")
public class Topic {

    @Column(primaryKey = true)
    private String id;
    private Integer stars;
    private String title;
    private LocalDateTime createTime;
}


@Controller
@Mapping("/test")
public class TestController {

    /**
     * 注意必须是配置多数据源的其中一个
     */
    @Db("db1")
    private EasyQuery easyQuery;
    @Mapping(value = "/hello",method = MethodType.GET)
    public String hello(){
        return "Hello World";
    }
    @Mapping(value = "/queryTopic",method = MethodType.GET)
    public Object queryTopic(){
        return easyQuery.queryable(Topic.class)
                .where(o->o.ge(Topic::getStars,2))
                .toList();
    }

额外配置

逻辑删除


public class MyLogicDelStrategy extends AbstractLogicDeleteStrategy {
    /**
     * 允许datetime类型的属性
     */
    private final Set<Class<?>> allowTypes=new HashSet<>(Arrays.asList(LocalDateTime.class));
    @Override
    protected SQLExpression1<WherePredicate<Object>> getPredicateFilterExpression(LogicDeleteBuilder builder, String propertyName) {
        return o->o.isNull(propertyName);
    }

    @Override
    protected SQLExpression1<ColumnSetter<Object>> getDeletedSQLExpression(LogicDeleteBuilder builder, String propertyName) {
//        LocalDateTime now = LocalDateTime.now();
//        return o->o.set(propertyName,now);
        //上面的是错误用法,将now值获取后那么这个now就是个固定值而不是动态值
        return o->o.set(propertyName, LocalDateTime.now());
    }

    @Override
    public String getStrategy() {
        return "MyLogicDelStrategy";
    }

    @Override
    public Set<Class<?>> allowedPropertyTypes() {
        return allowTypes;
    }
}


@Configuration
public class DemoConfiguration {
    @Bean(name = "db1",typed=true)
    public DataSource db1DataSource(@Inject("${db1}") HikariDataSource dataSource){
        return dataSource;
    }
    @Bean
    public void db1QueryConfiguration(@Db("db1") QueryConfiguration configuration){
        configuration.applyLogicDeleteStrategy(new MyLogicDelStrategy());
//        configuration.applyEncryptionStrategy(...);
//        configuration.applyInterceptor(...);

//        configuration.applyValueConverter(...);
//        configuration.applyValueUpdateAtomicTrack(...);
    }
    
}

Solon所有配置

针对单个数据源进行配置,如果需要影响到所有数据源看下面的影响到所有数据源

@Configuration
public class DemoConfiguration {
    @Bean(name = "db1",typed=true)
    public DataSource db1DataSource(@Inject("${db1}") HikariDataSource dataSource){
        return dataSource;
    }

//    /**
//     * 配置额外插件,比如自定义逻辑删除,加密策略,拦截器,分片初始化器,值转换,原子追踪更新
//     * @param configuration
//     */
//    @Bean
//    public void db1QueryConfiguration(@Db("db1") QueryConfiguration configuration){
//        configuration.applyLogicDeleteStrategy(new MyLogicDelStrategy());
//        configuration.applyEncryptionStrategy(...);
//        configuration.applyInterceptor(...);
//        configuration.applyShardingInitializer(...);
//        configuration.applyValueConverter(...);
//        configuration.applyValueUpdateAtomicTrack(...);
//    }

//    /**
//     * 添加分表或者分库的路由,分库数据源
//     * @param runtimeContext
//     */
//    @Bean
//    public void db1QueryRuntimeContext(@Db("db1") QueryRuntimeContext runtimeContext){
//        TableRouteManager tableRouteManager = runtimeContext.getTableRouteManager();
//        DataSourceRouteManager dataSourceRouteManager = runtimeContext.getDataSourceRouteManager();
//        tableRouteManager.addRoute(...);
//        dataSourceRouteManager.addRoute(...);
//
//        DataSourceManager dataSourceManager = runtimeContext.getDataSourceManager();
//
//        dataSourceManager.addDataSource(key, dataSource, poolSize);
//    }
}

配置影响到所有的数据源

public class App {
    public static void main(String[] args) {
        Solon.start(App.class,args,app->{
            app.onEvent(EasyQueryBuilderConfiguration.class,e->{
                //如果需要区分数据源可以通过e.getName()来区分
                e.replaceServiceFactory(QueryConfiguration.class, s->{
                    QueryConfiguration queryConfiguration = new QueryConfiguration(s.getService(EasyQueryOption.class)
                            ,s.getService(Dialect.class)
                            ,s.getService(NameConversion.class)
                            ,s.getService(EasyTimeJobManager.class)
                    );
//                    queryConfiguration.applyInterceptor();
//                    queryConfiguration.applyLogicDeleteStrategy();
//                    queryConfiguration.applyValueConverter();
                    return queryConfiguration;
                });
            });
        });
    }
