ABP+NetCore+Vue.js实现增删改查
ABP我就不多介绍了，不知道的可以自己百度
本篇开发工具VS2017，数据库SQL SERVER2012，系统Win7
1、去ABP官网下载对应的模板，下载地址：https://aspnetboilerplate.com/Templates
2、用VS2017打开解压后的项目，找到src下web项目下appsettings.json文件。打开后修改数据库连接字符串
图我就不截了，涉及个人隐私
3、在Core项目下添加二个文件夹，一个Entities文件夹存放所有的实体，一个IRepositories文件夹存放所有的仓储接口
IRepositories文件夹里面的仓储接口主要是自己定义除IRepository<TEntity, TPrimaryKey>没有定义的接口，本文的增删改查IRepository<TEntity, TPrimaryKey>都已经定义了，
所以IRepositories文件夹里面东西对本文作用不大，但是作为一名高度强迫症患者，还是添加此文件夹以备不时之需
附IRepository<TEntity, TPrimaryKey>定义的接口

}

4、自定义实体类User和仓储接口IUserRepository
using Abp.Domain.Entities;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Text; namespace Ocean.Entities
{
public class User : Entity
{
/// <summary>
/// 用户名
/// </summary>
[MaxLength()]
public virtual string UserName { get; set; } /// <summary>
/// 真实姓名
/// </summary>
[MaxLength()]
public virtual string RealName { get; set; } /// <summary>
/// 邮箱
/// </summary>
[MaxLength()]
public virtual string Email { get; set; } /// <summary>
/// 添加时间
/// </summary>
public virtual DateTime CreationTime { get; set; } = DateTime.Now; /// <summary>
/// 用户状态
/// </summary>
public virtual int Status { get; set; } = ;
}
}
using Abp.Domain.Repositories;
using System;
using System.Collections.Generic;
using System.Text; namespace Ocean.IRepositories
{
public interface IUserRepository : IRepository
{
//自定义除增删改查基本操作之外的其余方法接口
}
}
5、去EntityFrameworkCore下EntityFrameworkCore文件夹里添加个Repositories文件夹，里面主要存放实现自定义仓储接口的方法
using Ocean.IRepositories;
using System;
using System.Collections.Generic;
using System.Text; namespace Ocean.EntityFrameworkCore.Repositories
{
public class UserRepository : IUserRepository
{
//
}
}
6、EntityFrameworkCore下找到 DbContext文件打开，添加对应的DbSet
using Abp.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
using Ocean.Entities; namespace Ocean.EntityFrameworkCore
{
public class OceanDbContext : AbpDbContext
{
//Add DbSet properties for your entities...
public virtual DbSet<User> User { get; set; } public OceanDbContext(DbContextOptions<OceanDbContext> options)
: base(options)
{
//
}
}
}
7、打开工具--Nuget包管理器--程序包管理器控制台，默认项目选择EntityFrameworkCore并设定Web为解决方案的启动项目
执行命令 Add-Migration InitialCreate
成功后看Migrations文件夹里面生成的文件
然后执行命令 Update-Database
成功后就可以看到在数据库中生成的数据库和表了
8、来到Application项目中，添加一个定义的实体类文件夹，并在文件夹中添加一个IAppservice接口和一个AppService类
using Abp.Application.Services;
using System;
using System.Collections.Generic;
using System.Text; namespace Ocean.User
{
public interface IUserAppService : IApplicationService
{
List<Entities.User> GetUsers(); void UpdateUser(Entities.User entity); void CreateUser(Entities.User entity); void DeleteUser(int Id);
}
}
using Abp.Domain.Repositories;
using Ocean.Entities;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace Ocean.User
{
public class UserAppService : OceanAppServiceBase, IUserAppService
{
private readonly IRepository<Entities.User> _UserRepository;
public UserAppService(IRepository<Entities.User> userRepository)
{
_UserRepository = userRepository;
} public void CreateUser(Entities.User entity)
{
Logger.Info($"Created a User for entity at:{DateTime.Now}");
try
{
_UserRepository.Insert(entity);
}
catch (Exception ex)
{
Logger.Error(ex.ToString());
}
} public void DeleteUser(int Id)
{
Logger.Info($"Deleted a User for Id at:{DateTime.Now}");
try
{
_UserRepository.Delete(Id);
}
catch (Exception ex)
{
Logger.Error(ex.ToString());
}
} public List<Entities.User> GetUsers()
{
List<Entities.User> list = new List<Entities.User>();
Logger.Info($"Get Users List at:{DateTime.Now}");
try
{
list = _UserRepository.GetAll().ToList();
}
catch (Exception ex)
{
Logger.Error(ex.ToString());
}
return list;
} public void UpdateUser(Entities.User entity)
{
Logger.Info($"Updated a User for entity at:{DateTime.Now}");
try
{
_UserRepository.Update(entity);
}
catch (Exception ex)
{
Logger.Error(ex.ToString());
}
}
}
}
9、来到Web目录下，找到brower.json文件，右击选择管理Brower程序包，然后搜索Vue添加，这样就把Vue.js添加到项目中了
10、修改Startup下的OceanNavigationProvider文件，添加代码
public override void SetNavigation(INavigationProviderContext context)
{
context.Manager.MainMenu
.AddItem(
new MenuItemDefinition(
PageNames.Home,
L("HomePage"),
url: "",
icon: "fa fa-home"
)
).AddItem(
new MenuItemDefinition(
PageNames.About,
L("About"),
url: "Home/About",
icon: "fa fa-info"
)
).AddItem(
new MenuItemDefinition(
PageNames.User,
L("User"),
url: "User/Index",
icon: "fa fa-user"
)
);
}
别忘了打开PageNames文件，添加代码
public class PageNames
{
public const string Home = "Home";
public const string About = "About";
public const string User = "User";
}
11、在Controller文件夹添加控制器UserController
namespace Ocean.Web.Controllers
{
public class UserController : OceanControllerBase
{
// GET: /<controller>/
public ActionResult Index()
{
return View();
}
}
}
并在Views文件夹添加User文件夹并添加Index.cshtml
@using Ocean.Web.Startup
@{
ViewBag.ActiveMenu = PageNames.User;
} <div id="userApp">
<div class="row">
<div class="col-md-12">
<button data-toggle="modal" data-target="#userModal" class="btn btn-primary pull-right"><i class="fa fa-plus"></i>添加用户</button>
</div>
</div>
<div class="row">
<table class="table">
<thead>
<tr>
<th>用户Id</th>
<th>用户名</th>
<th>真实姓名</th>
<th>用户邮箱</th>
</tr>
</thead>
<tbody>
<tr v-for="user in userList">
<td><a href="javascript:void(0)" v-on:click="updateUser(user)">{{user.id}}</a></td>
<td>{{user.userName}}</td>
<td>{{user.realName}}</td>
<td>{{user.email}}</td>
</tr>
</tbody>
</table>
</div> <div class="modal fade" id="userModal" tabindex="-1" role="dialog" data-backdrop="static">
<div class="modal-dialog" role="document">
<div class="modal-content">
<form name="userForm" role="form" novalidate class="form-validation">
<div class="modal-header">
<h4 class="modal-title">
<span v-if="userModel.id">编辑用户</span>
<span v-if="!userModel.id">添加用户</span>
</h4>
</div>
<div class="modal-body">
<input type="hidden" v-model="userModel.id" />
<div class="form-group">
<label>用户名</label>
<input class="form-control" type="text" v-model="userModel.userName" required>
</div>
<div class="form-group">
<label>真实姓名</label>
<input class="form-control" type="text" v-model="userModel.realName" required>
</div>
<div class="form-group">
<label>用户邮箱</label>
<input class="form-control" type="text" v-model="userModel.email" required>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">@L("Cancel")</button>
<button type="button" class="btn btn-primary blue" v-on:click="createUser"><i class="fa fa-save"></i> <span>@L("Save")</span></button>
</div>
</form>
</div>
</div>
</div>
</div> @section scripts{
<script src="~/lib/vue/dist/vue.js"></script>
<script src="~/js/views/user/index.js"></script>
}
对应位置添加js文件
//abp的调用接口abp.services.app.user
var _userService = abp.services.app.user;
var appVue = new Vue({
el: "#userApp",
data: {
userModel: {
id: 0,
userName: '',
realName: '',
email: ''
},
userList: []
},
methods: {
getUsers: function () {
var own = this;
_userService.getUsers().done(function (result) {
own.userList = result;
});
},
createUser: function () {
var own = this;
if (own.userModel.id > 0) {
_userService.updateUser(own.userModel).done(function () {
location.reload();
})
}
else {
_userService.createUser(own.userModel).done(function () {
location.reload();
});
}
},
updateUser: function (user) {
var own = this;
own.userModel = user;
$('#userModal').modal();
}
}
});
appVue.getUsers();
最终效果图
最后：增改查都实现了，就是删除没有实现。删除的实现就靠你们了。我要去巩固Vue.js了
