Question

我的模型名为贷款：

public class Loan {
    private int loan_id;
    private String clientName;
    private String clientSurname;
    private Double amount;
    private int days;
    //getters and setters
}

和控制器

@RestController
public class MyController {

@Autowired
MyService myService;


@RequestMapping(value = "/makeAction",method = RequestMethod.POST)
public String makeLoan(){
     return myService.makeAction(...);
}

}

问题是：如何通过地址栏绕过多个变量，如：

本地主机：8080 / makeAction的LoanID = 1＃CLIENTNAME = Stive＃clientSurname = Wassabi

等等。

UPD：另一次尝试失败了：

    @RequestMapping(value="/makeLoan",method = RequestMethod.GET)
    public String makeLoan(@PathVariable("loan_id")int loan_id,
                           @PathVariable("name") String clientName,
                           @PathVariable("surname") String clientSurname,
                           @PathVariable("amount") double amount,
                           @PathVariable("days") int days ) throws Exception {
      return myService.makeLoan(loan_id,clientName,clientSurname,amount,days);

P.S尝试@PathVariables - 未能使用

Answer 1

谢谢大家帮助我解决这个问题

最终代码如下：

@RequestMapping(value = "/makeAction")
    public String makeLoan(@RequestParam("loan_id")int loan_id,
                           @RequestParam("clientName")String clientName,
                           @RequestParam("clientSurname")String clientSurname,
                           @RequestParam("amount")double amount,
                           @RequestParam("days")int days ) throws Exception {
        return loanService.makeAction(loan_id,clientName,clientSurname,amount,days);
    }

我必须删除GET / POST方法并将@PathVariable切换为@RequestParam

Answer 2

在您的方法中，使用RequestParam注释定义它们，如：

public String makeLoan(@RequestParam(value="clientName", required=false) String clientName) {//and others, and hope you meant & to seperate request parameters.
}

Answer 3

首先，您不应该在URL中输入POST参数。

网址参数用于GET，它们用＆amp;分隔。所以在你的情况下：

localhost:8080/makeAction?loanId=1&clientName=Stive&clientSurname=Wassabi

对于POST，您应该提交参数作为请求正文参数。参数与@SMA建议的@RequestParam注释绑定。

好吧，假设您使用的是Spring MVC，这可能会有所帮助： How to explictely obtain post data in Spring MVC?

请注意，如果您正在使用POST方法，则应在请求正文中读取您的参数...
