Map userMap1 = userList.stream().collect(Collectors.toMap(User::getId,User::getName));...System.out.println("1->"+userMap1); //2、list转map 指定key-value，key为属性值，value是对象本身...Map userMap2 = userList.stream().collect(Collectors.toMap(User::getId,User->User));...System.out.println("2->"+userMap2); //3、list转map 指定key-value，value是对象本身，Function.identity()是简洁写法...())); System.out.println("3->"+userMap3); //4、指定key-value，value是对象本身，Function.identity

但是后台返回只是text格式，需要转json格式： JSONObject jsonObject = JSON.parseObject(JSON.toJSONString(userMap...Long.parseLong(request.getParameter("para")); log.info("打印para的参数值"+userId); Map userMap...", userMap); JSONObject jsonObject = JSON.parseObject(JSON.toJSONString(userMap)); log.info...Long.parseLong(request.getParameter("para")); log.info("打印para的参数值"+userId); Map userMap...", userMap); JSONObject jsonObject = JSON.parseObject(JSON.toJSONString(userMap)); log.info
return */ User queryById(int userId); } 以上是实体类、dao层的设计以及在UserDao.xml中queryById方法的sql语句的编写，因为不论用association的哪种方式，sql语句都是一样的写，不同的只是userMap...property="address" column="address"/> <resultMap type="User" id="<em>userMap</em>...3、第三种方法:嵌套resultMap简化版 <result property="userName" column
