Restful传递数组参数的两种方式

第一种，直接传递数组

• js直接传递数组

var data = ["123","456"];
that.loadDictionarys(data).subscribe({
    next: res => {  }, error: err => { } });

• 后端接口直接接收数组

@POST
    @Path("/loadDictionarys")
    @Produces({ MediaType.APPLICATION_JSON, FastJSONProvider.TEXT_JSON, FastJSONProvider.TEXT_FASTJSON })
    public RestResponse loadDictionarys(String[] dicItemCodeArr) {
            Map<String, DictionaryVO> dictionaryVOs = new HashMap<>();
            RestResponse successResult = RestResponse.successResult(dictionaryVOs);
            return successResult;
    }

第二种，通过json对象传递

• js组装json对象传递数组

var data = {
　　arr:["123","456"]
};

that.loadDictionarys(data).subscribe({
    next: res => {      
    },
    error: err => {
    }
});

• 后端接口通过@FormParam注解可用String集合接收

@POST
    @Path("/loadDictionarys") @Produces({ MediaType.APPLICATION_JSON, FastJSONProvider.TEXT_JSON, FastJSONProvider.TEXT_FASTJSON }) public RestResponse loadDictionarys(@FormParam("arr") List<String> arr) { Map<String, DictionaryVO> dictionaryVOs = new HashMap<>(); RestResponse successResult = RestResponse.successResult(dictionaryVOs); return successResult; }
