Use WebMan technology to create an intelligent electronic contract system

With the rapid development of information technology, traditional paper contracts are gradually replaced by electronic contracts, becoming a A commonly used form of contract in the industry. Electronic contracts are not only convenient and efficient, but also ensure the authenticity, integrity and non-repudiation of the contract. In order to improve the efficiency of electronic contract processing and reduce the occurrence of disputes, the introduction of intelligent technology has become a top priority. This article will introduce how to use WebMan technology to create an intelligent electronic contract system, and attach corresponding code examples.

WebMan is a Web-based management system development framework that can quickly build enterprise-level applications with high scalability, flexibility and security. We can use WebMan technology to build the backend management platform of the electronic contract system to realize contract management, review, query and other functions. Below we will introduce it step by step.

First, we need to create a project based on WebMan and complete the corresponding environment configuration. Here we take Java as an example to briefly introduce how to create a Java project based on WebMan. First, we need to create a new Java project in the IDE and add the WebMan dependency library. Next, we create a web application named "contract" in the project and place all relevant code and resource files in the application.

In our electronic contract system, each contract will have the corresponding contract number, signing time, signing parties and other basic information. In order to achieve intelligent contract management, we also need to add some additional attributes to each contract, such as contract status, contract amount, validity period, etc. We can use WebMan's data modeling tool to create the contract's data model and generate the corresponding database table structure.

After creating the data model, we need to implement the core functions of the electronic contract system. First, we can use WebMan's form designer to design the contract entry interface to facilitate users to enter contract information. Next, we need to write corresponding controllers and service classes to handle operations such as contract submission, saving, and review. These operations can be achieved through the API interface provided by WebMan. Taking Java as an example, the following is a simple contract controller example:

@RestController
@RequestMapping("/contract")
public class ContractController {

    @Autowired
    private ContractService contractService;

    @PostMapping("/submit")
    public Object submitContract(@RequestBody Contract contract) {
        contract.setStatus("待审核");
        contract.setCreateTime(new Date());
        return contractService.saveContract(contract);
    }

    @GetMapping("/list")
    public Object listContracts() {
        return contractService.listContracts();
    }

    // 其他操作方法...
}

In the example, we use the @RestController annotation to declare the class as a controller, and define the URL of the interface through the @RequestMapping annotation path. In the submitContract method, we accept the contract parameters from the front end, set the status of the contract to "pending review", set the creation time of the contract to the current time, and then call the saveContract method of contractService to save the contract. In the listContracts method, we call the listContracts method of contractService to obtain the contract list.

In addition to contract entry and management, we can also implement some other functions, such as contract query, export and printing, etc. We can write the corresponding query interface and call the contractService method to implement these functions. In addition, we can also combine WebMan's report designer to generate various statistical charts and reports to provide more support for contract management.

To sum up, by using WebMan technology, we can quickly build an intelligent electronic contract system to realize contract management, review, query and other functions. Through the above code examples, I believe readers can better understand how to use WebMan technology to implement an intelligent contract system. I hope this article has provided some help to readers in building their own electronic contract systems.
