Question

我是ajax的新手。我找到了许多类似的答案，但我无法弄清楚为什么我的请求在语法上不正确。这是我的代码： ajax代码：

@RequestMapping(value = "/remove-contacts", method=RequestMethod.POST)
@ResponseBody
public Long[] removeConnections(@RequestParam(value="userIds") String[] userIds, HttpServletRequest request) throws Exception {
    //some code
    return null;
}

Spring控制器：

/Users/me/my_teams_code/some_project/package/IWantThisClass.py

请帮我弄清楚我的错误。抱歉英文不好

RequestParam不正确，您应该使用@RequestBody。从高级别来看，您应该创建一个包含数组的POJO对象。

public class POJO {

    private String[] userIds;

    public POJO() {
    }

    /**
     * @return the userIds
     */
    public String[] getUserIds() {
        return userIds;
    }

    /**
     * @param userIds the userIds to set
     */
    public void setUserIds(String[] userIds) {
        this.userIds = userIds;
    }
}

    @RequestMapping(value = "/remove-contacts", method=RequestMethod.POST)
    @ResponseBody
    public Long[] removeConnections(@RequestBody POJO pojo, HttpServletRequest request) throws Exception {
        //some code
        return null;
    }

通过ajax将数组传递给spring控制器
