关于RestTemplate的一些小测试，大家可以来说说原理~~~

001：参数为int

@DeleteMapping(value = "deleteUserByIds")
    public void deleteAllByIds(int[] ids){
        System.out.println("users is deleting。。。");
        for (int id : ids) {
            System.out.print(id+"  ");
        }
    }

test：运行1 可正常执行运行2 会报null指针，参数传不过来

public class testRestTemplate {
    @Autowired
    private RestTemplate restTemplate;

    @Test
    public void deleteUser(){
        int[] ids = new int[]{1,7,5,6,8};
        //1.restTemplate.delete("http://localhost:8000/deleteUserByIds?ids=[1,4]");
        //2.restTemplate.delete("http://localhost:8000/deleteUserByIds","1,5,7,8,4");
    }

002：参数为String：

@DeleteMapping(value = "deleteUserByIds")
    public void deleteAllByIds(int[] ids){
        System.out.println("users is deleting。。。");
        for (int id : ids) {
            System.out.print(id+"  ");
        }
    }

test：只有1成功，其他都为null

public class testRestTemplate {
    @Autowired
    private RestTemplate restTemplate;

    @Test
    public void deleteUser(){
        int[] ids = new int[]{1,7,5,6,8};
        String[] idss = new String[]{"3","2","5"};
        //1.restTemplate.delete("http://localhost:8000/deleteUserByIds?ids=[1,4]");
        //2.restTemplate.delete("http://localhost:8000/deleteUserByIds","1,5,7,8,4");
        //3.restTemplate.delete("http://localhost:8000/deleteUserByIds",ids);
        //4.restTemplate.delete("http://localhost:8000/deleteUserByIds",idss);

    }

暂时一脸懵逼，求大佬解释一下，或者等以后有了解了再回来解决一下 hahh
