前提使用springboot 2.1.7 Mybatis-plus

测试1：测试前displayd = 1 ==>测试后任为1 发生了回滚（未进行try-catch）

    @Override
    @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
    public void updateFactory(String factoryId) {
        lambdaUpdate().eq(FactoryPO::getId, factoryId)
                .set(FactoryPO::getDisplayd, Boolean.FALSE)
                .update();
        String str = null;
        str.equals(factoryId);
    }

结果：

测试2：测试前displayd = 1 ==>测试后为0 未发生了回滚（进行try-catch）

    @Override
    @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
    public void updateFactory(String factoryId) {
        lambdaUpdate().eq(FactoryPO::getId, factoryId)
                .set(FactoryPO::getDisplayd, Boolean.FALSE)
                .update();
        String str = null;
        try{
            str.equals(factoryId);
        }catch (Exception e){
            e.printStackTrace();
        }
    }

结果：

测试3：测试前displayd = 1, deleted = 0, updateFactory方法中调deleteFactory方法，displayd和deleted没有修改，回滚

@Override
    @Transactional(rollbackFor = Exception.class)
    public void updateFactory(String factoryId) {
        lambdaUpdate().eq(FactoryPO::getId, factoryId)
                .set(FactoryPO::getDisplayd, Boolean.FALSE)
                .update();
        deleteFactory(factoryId);
    }

    @Override
    public void deleteFactory(String factoryId) {
        removeById(factoryId);
        String str = null;
        str.equals(factoryId);
    }

结果

测试4：测试前displayd = 1, deleted = 0, updateFactory方法中调deleteFactory方法，displayd = 0,deleted=1,未回滚

    @Override
    public void updateFactory(String factoryId) {
        lambdaUpdate().eq(FactoryPO::getId, factoryId)
                .set(FactoryPO::getDisplayd, Boolean.FALSE)
                .update();
        deleteFactory(factoryId);
    }

    @Override
    @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
    public void deleteFactory(String factoryId) {
        removeById(factoryId);
        String str = null;
        str.equals(factoryId);
    }

结果
