為便於在工作中進行單機多服務部署及簡化開發配置，將現有系統遷移至Spring boot。

Maven配置

       Spring boot相關依賴：web、jdbc、aop相關依賴包（由於專案中應用了redis，所以一併移植了）

MyBatis配置相關

       mapper配置檔案存放於resources目錄：

resources/
     mapper/
         xxx.xml
         xxx.xml
         ...

整合Spring boot 配置檔案:MyBatisConfig,MyBatisMapperScannerConfig。
參考：abel MyBatis整合

@Configuration
@EnableTransactionManagement
public class MyBatisConfig implements TransactionManagementConfigurer {


    @Autowired
    XbDataSource xbDataSource;//整合sharding-jdbc分表資料來源

    @Bean(name = "sqlSessionFactory")
    public SqlSessionFactory sqlSessionFactoryBean() {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(xbDataSource.getDataSource());
        bean.setTypeAliasesPackage("com.xiaobai.crawler.model");//實體對應包路徑


        ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        try {
            bean.setMapperLocations(resolver.getResources("classpath:mapper/*.xml"));
            return bean.getObject();
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }

    @Bean
    public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

    @Bean
    @Override
    public PlatformTransactionManager annotationDrivenTransactionManager() {

        return new DataSourceTransactionManager(xbDataSource.getDataSource());
    }
}

@Configuration
@AutoConfigureAfter(MyBatisConfig.class)
public class MyBatisMapperScannerConfig {

    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer() {
        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
        mapperScannerConfigurer.setBasePackage("com.xiaobai.crawler.mapper");//mapper類路徑
        return mapperScannerConfigurer;
    }

}

sharding-jdbc分表配置

資料來源配置及分表規則定義(只對tb_p表按照item_id進行分表13張，tb_item不分表)

@Component
public class XbDataSource {

    @Autowired
    DataSource dataSource;

    DataSource shardingDataSource;

    @PostConstruct
    public void init() {
        HashMap<String, DataSource> map = new HashMap<>();
        map.put("dataSource", dataSource);
        DataSourceRule dataSourceRule = new DataSourceRule(map);

        List<TableRule> tableRuleList = new ArrayList<>();
        List<String> pList = new ArrayList<>();
        for (int i = 1; i < 14; i++) {
            pList.add("tb_p_" + i);
        }
        //tb_p邏輯表名，pList實際所有的分表
        tableRuleList.add(new TableRule.TableRuleBuilder("tb_p")
                .actualTables(pList)
                .dataSourceRule(dataSourceRule)
                .tableShardingStrategy(new TableShardingStrategy("item_id", new ProgramShardingAlgorithm())).build());
        tableRuleList.add(new TableRule.TableRuleBuilder("tb_item")
                .actualTables(Lists.newArrayList("tb_item"))
                .dataSourceRule(dataSourceRule).build());
        ShardingRule shardingRule = ShardingRule.builder()
                .dataSourceRule(dataSourceRule)
                .tableRules(tableRuleList)
                .build();
        shardingDataSource = ShardingDataSourceFactory.createDataSource(shardingRule);
    }

    public DataSource getDataSource() {
        return shardingDataSource;
    }

@Component

        Collection<String> result = new LinkedHashSet<String>(availableTargetNames.size());
        Collection<Integer> values = shardingValue.getValues();

        Collection<String> result = new LinkedHashSet<String>(availableTargetNames.size());
        Range<Integer> range = shardingValue.getValueRange();
        for (Integer i = range.lowerEndpoint(); i <= range.upperEndpoint(); i++) {
            for (String each : availableTargetNames) {
                if (each.endsWith(i % 14+ "")) {
                    result.add(each);
                }
            }
        }
        return result;
