GET请求如何传递数组参数

方式一

可以将数组参数传递多次，springmvc会将多个同名参数自动封装成数组或者集合对象，示例如下：

# 请求URL
http://127.0.0.1:8080/getUsers?name=张三&name=李四

# 后台接口代码
@RestController
@RequestMapping("/")
public class SpringMvcController {

    @RequestMapping(value = "/getUsers", method = RequestMethod.GET)
    # String[] name也可以切换为List<String,String> name
    public String getUsers(@RequestParam String[] name) {
        return name[0] + "  " + name[1];
    }
}

方式二、

直接将数组指用逗号分隔，示例如下：

# 请求URL
http://127.0.0.1:8080/getTeachers?name=王五,刘麻子

# 后台接口代码
@RestController
@RequestMapping("/")
public class SpringMvcController {

    @RequestMapping(value = "/getTeachers", method = RequestMethod.GET)
    # String[] name也可以切换为List<String,String> name
    public String getTeachers(@RequestParam String[] name) {
        return name[0] + "  " + name[1];
    }
}
