篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了10-2 图书管理系统（SSM+LayUi）相关的知识，希望对你有一定的参考价值。
返回响应信息工具类
- 在com.gychen.util里新建Constants和RestRespond
- Constants
package com.gychen.util; /** * 常量类 */ public class Constants { public final static int OK_CODE = 0; public final static int FAIL_CODE = 400; public final static int OTHER_FAIL_CODE = 333; public final static String OK_MSG = "请求成功"; public final static String FAIL_MSG = "请求失败"; public final static int STATUS_0 = 0; //可用状态 public final static int STATUS_1 = 1; //禁用状态 // 单个对象 public static final String ITEM = "item"; // 返回的对象列表 public static final String LIST = "list"; public final static String CACHE_NAME = "KACache"; }- RestRespond
package com.gychen.util; import java.util.HashMap; import java.util.List; /** * REST 接口返回数据 * * @author gychen */ public class RestResponse extends HashMap<String, Object> { /** * 禁止通过构造函数构造对象，只能通过静态方法获取实例。 * * @see #ok() * @see #ok(String) * @see #fail() * @see #fail(String) */ private RestResponse() { } /** * 设置接口返回的文本消息，属性 key: message * * @param msg * @return */ public RestResponse msg(String msg) { this.put(Constants.OK_MSG, msg); return this; } /** * 设置接口返回的数据对象，属性 key: item * * @param item * @return */ public RestResponse item(Object item) { this.put(Constants.ITEM, item); return this; } /** * 设置接口返回的数据对象列表，属性 key: list * * @param list * @return */ public RestResponse list(List<?> list) { this.put("data", list); return this; } /** * 设置接口返回的数据项，并指定数据项的属性 key * * @param key * @param value * @return */ public RestResponse put(String key, Object value) { super.put(key, value); return this; } /** * 接口执行成功的返回数据，其中属性 OK_CODE = 0 * * @return */ public static RestResponse ok() { RestResponse result = new RestResponse(); result.put("code", Constants.OK_CODE); result.put("msg", Constants.OK_MSG); return result; } /** * 接口执行成功的返回数据，并设置文本消息 * * @param msg * @return */ public static RestResponse ok(String msg) { RestResponse result = new RestResponse(); result.put("code", Constants.OK_CODE); result.put("msg", Constants.OK_MSG).msg(msg); return result; } /** * 接口执行成功的返回数据，并设置对象数据 * * @param item * @return */ public static RestResponse ok(Object item) { RestResponse result = new RestResponse(); result.put("msg", Constants.OK_MSG); result.put("code", Constants.OK_CODE).item(item); return result; } /** * 接口执行成功的返回数据，并设置列表对象数据 * * @param list * @return */ public static RestResponse ok(List<?> list) { RestResponse result = new RestResponse(); result.put("code", Constants.OK_CODE); result.put("msg",Constants.OK_MSG).list(list); return result; } /** * 接口执行失败的返回数据，其中属性 FIAL_CODE = 1 * * @return */ public static RestResponse fail() { RestResponse result = new RestResponse(); result.put("code", Constants.FAIL_CODE); result.put("msg", Constants.FAIL_MSG); return result; } /** * 接口执行失败的返回数据，并设置文本消息，其中属性 error = 1, message = {msg} * * @param msg * @return */ public static RestResponse fail(String msg) { RestResponse result = new RestResponse(); result.put("msg", Constants.FAIL_MSG); result.put("code", Constants.FAIL_CODE).msg(msg); return result; } /** * 接口执行失败的返回数据，自定义状态码，其中属性 error = {errcode} * * @param errcode * @return */ public static RestResponse fail(int errcode) { RestResponse result = new RestResponse(); result.put("msg", Constants.FAIL_MSG); result.put("code", errcode); return result; } }
新建TypeController
- 在com.gychen.controller里新建TypeController
package com.gychen.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class TypeController {
@RequestMapping("/typeIndex")
public String typeIndex(){
return "type/typeIndex";
}
/**
* 获取type数据信息 分页
*/
@RequestMapping("/typeAll")
@ResponseBody // 以json格式返回
public Object typeAll(){
return null;
}
}
修改typeIndex.jsp
- 添加jsp头文件和jstl、el、路径信息
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!-- 获取项目路径和项目其它信息 -->
<%
String path=request.getContextPath();
String basePath=request.getScheme()+
"://"+request.getServerName()+
":"+request.getServerPort()+path+
"/";
%>

});
</script>
修改ClassInfoDao
- 在com.gychen.dao里修改ClassInfoDao
package com.gychen.dao;
import com.gychen.po.ClassInfo;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Component;
import java.util.List;
@Component("classDao")
public interface ClassInfoDao {
/**
* 查询所有图书类型信息
*/
// @Select("select * from class_info")
// List<ClassInfo> queryClassInfoAll();
List<ClassInfo> queryClassInfoAll(@Param(value = "name")String name);
}
添加ClassInfoDao.xml
- 在resources/com.gychen.dao里新建ClassInfoDao.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.gychen.dao.ClassInfoDao" >
<!-- 查询全部信息 -->
<select id="queryClassInfoAll" resultType="com.gychen.po.ClassInfo">
select * from class_info
<where>
<if test="name!=null">
and name like ‘%${name}%‘
</if>
</where>
</select>
</mapper>
- 在ClassInfoService中修改接口信息
List<ClassInfo> queryClassInfoAll (@Param(value = "name")String name);
- 修改TypeController
package com.gychen.controller;
import com.github.pagehelper.PageInfo;
import com.gychen.po.ClassInfo;
import com.gychen.service.ClassInfoService;
import com.gychen.util.RestResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class TypeController {
@Autowired
private ClassInfoService classInfoService; // 这里的classInfoService要和ClassInfoServiceImpl中的注解名字相同
@RequestMapping("/typeIndex")
public String typeIndex(){
return "type/typeIndex";
}
/**
* 获取type数据信息 分页
*/
@RequestMapping("/typeAll")
@ResponseBody
public RestResponse typeAll(String name, @RequestParam(defaultValue = "1") Integer page,
@RequestParam(defaultValue = "15") Integer limit){
PageInfo<ClassInfo> pageInfo = classInfoService.queryClassInfoAll(name, page, limit);
return RestResponse.ok(pageInfo.getList());
}
}
- 修改typeindex.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
