使用mybatis plus动态数据源和sharding5.1.0报错 Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

根据提供的引用内容，报错信息显示缺少'sqlSessionFactory'或'sqlSessionTemplate'属性。这通常是因为Mybatis Plus无法自动注入SqlSessionFactory或SqlSessionTemplate实例。解决此问题的方法是手动注入SqlSessionFactory或SqlSessionTemplate实例。以下是使用Mybatis Plus动态数据源和Sharding 5.1.0的示例代码：

@Configuration
@MapperScan(basePackages = "com.example.mapper")
public class DataSourceConfig {
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.master")
    public DataSource masterDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.slave")
    public DataSource slaveDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean
    public DataSource dynamicDataSource() {
        DynamicDataSource dynamicDataSource = new DynamicDataSource();
        Map<Object, Object> dataSourceMap = new HashMap<>(2);
        dataSourceMap.put("master", masterDataSource());
        dataSourceMap.put("slave", slaveDataSource());
        dynamicDataSource.setDefaultTargetDataSource(masterDataSource());
        dynamicDataSource.setTargetDataSources(dataSourceMap);
        return dynamicDataSource;
    }

    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        MybatisSqlSessionFactoryBean sqlSessionFactoryBean = new MybatisSqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dynamicDataSource());
        sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:mapper/*.xml"));
        return sqlSessionFactoryBean.getObject();
    }

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

    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }

    @Bean
    public ShardingDataSource shardingDataSource() throws SQLException {
        ShardingRuleConfiguration shardingRuleConfig = new ShardingRuleConfiguration();
        shardingRuleConfig.getTableRuleConfigs().add(getOrderTableRuleConfiguration());
        shardingRuleConfig.getBindingTableGroups().add("t_order");
        shardingRuleConfig.setDefaultDatabaseShardingStrategyConfig(new StandardShardingStrategyConfiguration("user_id", new ModuloShardingDatabaseAlgorithm()));
        shardingRuleConfig.setDefaultTableShardingStrategyConfig(new StandardShardingStrategyConfiguration("order_id", new ModuloShardingTableAlgorithm()));
        Properties properties = new Properties();
        properties.setProperty("sql.show", "true");
        return ShardingDataSourceFactory.createDataSource(createDataSourceMap(), shardingRuleConfig, properties);
    }

    private TableRuleConfiguration getOrderTableRuleConfiguration() {
        TableRuleConfiguration result = new TableRuleConfiguration("t_order", "ds${0..1}.t_order_${0..1}");
        result.setDatabaseShardingStrategyConfig(new StandardShardingStrategyConfiguration("user_id", new ModuloShardingDatabaseAlgorithm()));
        result.setTableShardingStrategyConfig(new StandardShardingStrategyConfiguration("order_id", new ModuloShardingTableAlgorithm()));
        return result;
    }

    private Map<String, DataSource> createDataSourceMap() {
        Map<String, DataSource> result = new HashMap<>(2);
        result.put("ds0", masterDataSource());
        result.put("ds1", slaveDataSource());
        return result;
    }
}
