[学习交流] 【上海校区】基于springboot+bootstrap+mysql+redis搭建一套完整的...

大家在经过一段时间的开发实际上已经积累的自己的一套的开发框架或者一些自己的jar包，此处所编写的开发工具是基于当前工程的进行扩展的一个开发工具包，仅适合当前框架，若大家需要的话可以自己在当前开发工具包底下进行扩展，有了开发工具包的好处就是我们可以少写很多基础的代码，那么接下来将开始编写我们的开发工具包：

   首先在我们的common包底下先建以下的包结构：

在我们创建我们的开发工具包之前我们需要先添加几个配置文件在我们的config->util包底下我们创建一个json包同时增加一个JsonHelper.java文件如下所示：

/*
* 类描述：json工具类
* @auther linzf
* @create 2017/8/23 0023
*/
public class JsonHelper {

private static SimpleDateFormat sdf = new SimpleDateFormat(
         "yyyy-MM-dd HH:mm:ss");

// 将JSON转换成Map,其中valueClz为Map中value的Class,keyArray为Map的key
public static Map json2Map(Object[] keyArray, String json, Class valueClz) {
      JSONObject jsonObject = JSONObject.fromObject(json);
      Map classMap = new HashMap();
      for (int i = 0; i < keyArray.length; i++) {
         classMap.put(keyArray, valueClz);
      }
      return (Map) JSONObject.toBean(jsonObject, Map.class, classMap);
}

/***

}

接着改造我们的java层，首先在我们的sys包的entity底下创建一个QueryUser.java文件如下所示：

/**
*@author linzf
**/
public class QueryUser extends QueryBase {
private String login;
private String password;
private String userName;
private String address;
private String job;
private Long groupId;
private String birthDate;
private String city;
private String district;
private String province;
private String streetAddress;
private String state;
private String type;
private String lastLoginDate;

public String getLogin() {
return login;
}

public void setLogin(String login) {
this.login = login;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}

public String getJob() {
return job;
}

public void setJob(String job) {
this.job = job;
}

public Long getGroupId() {
return groupId;
}

public void setGroupId(Long groupId) {
this.groupId = groupId;
}

public String getBirthDate() {
return birthDate;
}

public void setBirthDate(String birthDate) {
this.birthDate = birthDate;
}

public String getCity() {
return city;
}

public void setCity(String city) {
this.city = city;
}

public String getDistrict() {
return district;
}

public void setDistrict(String district) {
this.district = district;
}

public String getProvince() {
return province;
}

public void setProvince(String province) {
this.province = province;
}

public String getStreetAddress() {
return streetAddress;
}

public void setStreetAddress(String streetAddress) {
this.streetAddress = streetAddress;
}

public String getState() {
return state;
}

public void setState(String state) {
this.state = state;
}

public String getType() {
return type;
}

public void setType(String type) {
this.type = type;
}

public String getLastLoginDate() {
return lastLoginDate;
}

public void setLastLoginDate(String lastLoginDate) {
this.lastLoginDate = lastLoginDate;
}

}
接着改造我们的UserDao如下所示：
/**
*@author linzf
**/
public interface UserDao extends GenericDao<User, QueryUser> {

/**
   * 功能描述：根据账号来获取用户信息
   * @param login
   * @return
   */
User findByLogin(String login);

}
接着在sys包底下创建一个service包，并创建UserService.java文件如下所示：
/*
* 类描述：
* @auther linzf
* @create 2017/12/8 0008
*/
@Service("userService")
@Transactional(rollbackFor={IllegalArgumentException.class})
public class UserService extends GenericService<User, QueryUser> {

@Autowired
@SuppressWarnings("SpringJavaAutowiringInspection")
private UserDao userDao;

@Override
protected GenericDao<User, QueryUser> getDao() {
      return userDao;
}
}

接着改造我们的controller层代码如下：
/*
* 类描述：用户维护controller
* @auther linzf
* @create 2017/9/7 0007
*/
@Controller
@RequestMapping("/user")
public class UserController extends GenericController<User,QueryUser> {

@Inject
private UserService userService;

@Override
protected GenericService<User, QueryUser> getService() {
      return userService;
}
}
配置好以后我们的整个的效果如下：

接着我们重新加载我们的代码并把整个项目运行起来，然后去访问我们的swagger2的目录，你会发现我们已经多了很多的功能了，以后我们有了新的模块的时候我们只需要继承我们的类就可以实现快速的开发了，效果如下：

      到此处我们完成了我们的基础开发工具的百分30的开发工作了，因为到这里我们还需要自己去编写我们的dao、service、controller以及mybatis配置文件，这个过程完全是一个干苦力的过程，因此在下一章我们将编写一个工具类来帮我们快速生成以上的代码，该项目的GitHub地址：https://github.com/185594-5-27/c ... id-swagger-tool-one。
