RESTful API 参数处理-优快云博客

1.@pathparam

    @GET  
    @Path("delProByPNumber/{param}")  
    @Produces("application/json; charset=utf-8")  
    public Response delPro(@PathParam("param") String  pNumber){  
        session.delete("production.delete", pNumber);  
        session.commit();  
        List list=queryAllPro();
        return Response.status(201).entity(list).build();  
    }  
    //访问路径：http://IP:PORT/应用上下文/delProByPNumber/7，其中7为传入参数

2.@queryParam

    @GET  
    @Path("addAcc/parameters")  
    @Produces("application/json; charset=utf-8")  
    public Response addCus(  
            @QueryParam("accname") String accname, 
            @QueryParam("department") String   department,
            @QueryParam("accnumber") long accnumber,  
            @QueryParam("username") String username  
            ) {  
        Account account=new Account();  
        account.setAccname(accname);  
        account.setDepartment(department); 
        account.setAccnumber(accnumber);  
        account.setUsername(username);  
        session.insert("account.addAcc",account);  
        session.commit();  
  
        return Response.status(201).entity(queryOne(accname)).build();  
    }  
    //访问路径：http://IP:PORT/应用上下文/addAcc/parameters?accname=rr&department=heda&accnumber=6666&username=yu

3.@FormParam

    //form表单提交方式  
    @POST  
    @Path("getName")  
    public String  getName(@FormParam("fname") String fname,@FormParam("lname") String lname) {  
        String result = "RESTEasy Hello World : " + fname+lname;  
        System.out.println("fname"+fname);  
        return result;  
    }

<!---前台form表单提交--->
<html>  
<head>  
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  
<title>Insert title here</title>  
</head>  
<body>  
    <form action="http://IP:PORT/应用上下文/getName" method="POST">  
        First name: <input type="text" name="fname" />  
        Last name: <input type="text" name="lname" />  
        <input type="submit" value="Submit" />  
    </form>  
</body>  
</html>

4.接收json参数，不需要标注

    @POST  
    @Path("test")  
    @Produces("application/json; charset=utf-8")  
    public Map<String, Object> getName(String data){  
        String name = null;  
        String password = null;  
        //解析传入json数据  
        ObjectMapper objectMapper = new ObjectMapper();  
        Map<String, Object> maps;  
        try {  
            maps = objectMapper.readValue(data, Map.class);  
            name = (String) maps.get("name");  
            password = (String) maps.get("password");  
        } catch (Exception e) {
            e.printStackTrace();  
        }
        //返回map  
        Map<String, Object> map = new HashMap<String, Object>();  
        map.put("name", name);  
        map.put("password", password);  
        return map;  
    }  
}
