Project actual combat: Central controller implementation (4) – implement the function of RequestBody annotation – obtain request body parameters

In order to retaliate confidently, I wrote a log aspect output interface input and output parameters.

1.Background In the process of daily troubleshooting, we know that incorrect input parameters are one of the common reasons for interface call failure. Especially the callback interface and openAPI interface provided for third-party calls. Since the level of third-party developers cannot be guaranteed, problems often arise. I repeatedly come to you to ask why it […]

Google visual language model PaLI-3 is released, with only 5B parameters, smaller, faster and stronger

Source: Heart of the Machine This article is about 3,000 words, it is recommended to read for 5 minutes This article introduces the Google visual language model PaLi-3. In the field of large multi-modal (visual language) models, while fighting for parameters to win performance, pursuing smaller parameters, faster speed, and stronger performance is another research […]

Use Spring Validation to verify parameters

I don’t know how you write the parameter verification of the controller layer in your usual business development process? Is there such a direct judgment as below? public String add(UserVO userVO) {<!– –> if(userVO.getAge() == null){<!– –> return “Age cannot be empty”; } if(userVO.getAge() > 120){<!– –> return “Age cannot exceed 120”; } if(userVO.getName().isEmpty()){<!– –> […]

The author is a junior student. This blog is used while learning. Please forgive me if there are any mistakes. Attach the code at the end of the article. 1. DH parameters The front coordinate system corresponds to the improved version: modified The post coordinate system corresponds to the standard version: standard Because most of […]

C++ uses boost to implement an asynchronous thread pool with return values and input parameters

Preface Thread pools have some advantages over simple multi-threading: 1. The thread pool will automatically allocate work to an idle worker thread for execution, which is better than multi-thread execution in batches; 2. The thread pool only needs to be created once. The creation and destruction of multiple threads when used multiple times will cause […]
