单元测试里用service插入没有异常，而且查询的结果没有问题
在调用service新插入时，实体类的自动生成的id也能正常返回
但是为什么数据库里却找不到？

    private static final Log log = Logs.get();
    ProductTypeService productTypeService;
    ProductService productService;
    ProductInventoryService productInventoryService;

    //获取类型的键值对，方便匹配
    private static NutMap typeMap;

    @Before
    public void _init() {
        if (productTypeService == null) {
            productTypeService = ioc.get(ProductTypeServiceImpl.class);
        }
        if (productService == null) {
            productService = ioc.get(ProductServiceImpl.class);
        }
        if (productInventoryService == null) {
            productInventoryService = ioc.get(ProductInventoryServiceImpl.class);
        }
        try {
            Trans.begin();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

这是日志：
