一、开发介绍

1.1 开发环境

• 开发语言：Java

• 数据库：MySQL

• 系统架构：B/S

• 后端：SpringBoot / SSM(Spring+SpringMVC+Mybatis)

• 前端：微信小程序+uniapp+Vue

• 工具：IDEA或者Eclipse、HBuilderX、JDK1.8、Maven

二、系统介绍

管理员后台页面：
功能：首页、个人中心、用户管理、教练管理、驾校信息管理、驾校车辆管理、教练预约管理、考试信息管理、预约考试管理、系统管理

三、部分代码设计

3.1.Mybatis-Plus工具类-部分代码如下：

/*** Mybatis-Plus工具类*/
public class MPUtil {public static final char UNDERLINE = '_';//mybatis plus allEQ 表达式转换public static Map allEQMapPre(Object bean,String pre) {Map<String, Object> map =BeanUtil.beanToMap(bean);return camelToUnderlineMap(map,pre);}//mybatis plus allEQ 表达式转换public static Map allEQMap(Object bean) {Map<String, Object> map =BeanUtil.beanToMap(bean);return camelToUnderlineMap(map,"");}public static Wrapper allLikePre(Wrapper wrapper,Object bean,String pre) {Map<String, Object> map =BeanUtil.beanToMap(bean);Map result = camelToUnderlineMap(map,pre);return genLike(wrapper,result);}public static Wrapper allLike(Wrapper wrapper,Object bean) {Map result = BeanUtil.beanToMap(bean, true, true);			 return genLike(wrapper,result);}public static Wrapper genLike( Wrapper wrapper,Map param) {Iterator<Map.Entry<String, Object>> it = param.entrySet().iterator();int i=0;while (it.hasNext()) {if(i>0) wrapper.and();Map.Entry<String, Object> entry = it.next();String key = entry.getKey();String value = (String) entry.getValue();wrapper.like(key, value);i++;}return wrapper;}public static Wrapper likeOrEq(Wrapper wrapper,Object bean) {Map result = BeanUtil.beanToMap(bean, true, true);			 return genLikeOrEq(wrapper,result);}public static Wrapper genLikeOrEq( Wrapper wrapper,Map param) {Iterator<Map.Entry<String, Object>> it = param.entrySet().iterator();int i=0;while (it.hasNext()) {if(i>0) wrapper.and();Map.Entry<String, Object> entry = it.next();String key = entry.getKey();if(entry.getValue().toString().contains("%")) {wrapper.like(key, entry.getValue().toString().replace("%", ""));} else {wrapper.eq(key, entry.getValue());}i++;}return wrapper;}public static Wrapper allEq(Wrapper wrapper,Object bean) {Map result = BeanUtil.beanToMap(bean, true, true);			 return genEq(wrapper,result);}public static Wrapper genEq( Wrapper wrapper,Map param) {Iterator<Map.Entry<String, Object>> it = param.entrySet().iterator();int i=0;while (it.hasNext()) {if(i>0) wrapper.and();Map.Entry<String, Object> entry = it.next();String key = entry.getKey();wrapper.eq(key, entry.getValue());i++;}return wrapper;}public static Wrapper between(Wrapper wrapper,Map<String, Object> params) {for(String key : params.keySet()) {String columnName = "";if(key.endsWith("_start")) {columnName = key.substring(0, key.indexOf("_start"));if(StringUtils.isNotBlank(params.get(key).toString())) {wrapper.ge(columnName, params.get(key));}}if(key.endsWith("_end")) {columnName = key.substring(0, key.indexOf("_end"));if(StringUtils.isNotBlank(params.get(key).toString())) {wrapper.le(columnName, params.get(key));}}}return wrapper;}public static Wrapper sort(Wrapper wrapper,Map<String, Object> params) {String order = "";if(params.get("order") != null && StringUtils.isNotBlank(params.get("order").toString())) {order = params.get("order").toString();}if(params.get("sort") != null && StringUtils.isNotBlank(params.get("sort").toString())) {if(order.equalsIgnoreCase("desc")) {wrapper.orderDesc(Arrays.asList(params.get("sort")));} else {wrapper.orderAsc(Arrays.asList(params.get("sort")));}}return wrapper;}/*** 驼峰格式字符串转换为下划线格式字符串* * @param param* @return*/public static String camelToUnderline(String param) {if (param == null || "".equals(param.trim())) {return "";}int len = param.length();StringBuilder sb = new StringBuilder(len);for (int i = 0; i < len; i++) {char c = param.charAt(i);if (Character.isUpperCase(c)) {sb.append(UNDERLINE);sb.append(Character.toLowerCase(c));} else {sb.append(c);}}return sb.toString();}public static void main(String[] ages) {System.out.println(camelToUnderline("ABCddfANM"));}public static Map camelToUnderlineMap(Map param, String pre) {Map<String, Object> newMap = new HashMap<String, Object>();Iterator<Map.Entry<String, Object>> it = param.entrySet().iterator();while (it.hasNext()) {Map.Entry<String, Object> entry = it.next();String key = entry.getKey();String newKey = camelToUnderline(key);if (pre.endsWith(".")) {newMap.put(pre + newKey, entry.getValue());} else if (StringUtils.isEmpty(pre)) {newMap.put(newKey, entry.getValue());} else {newMap.put(pre + "." + newKey, entry.getValue());}}return newMap;}
}

3.2.校验工具类-部分代码如下：

/*** hibernate-validator校验工具类*/
public class ValidatorUtils {private static Validator validator;static {validator = Validation.buildDefaultValidatorFactory().getValidator();}/*** 校验对象* @param object        待校验对象* @param groups        待校验的组* @throws EIException  校验不通过，则报EIException异常*/public static void validateEntity(Object object, Class<?>... groups)throws EIException {Set<ConstraintViolation<Object>> constraintViolations = validator.validate(object, groups);if (!constraintViolations.isEmpty()) {ConstraintViolation<Object> constraint = (ConstraintViolation<Object>)constraintViolations.iterator().next();throw new EIException(constraint.getMessage());}}}

3.3.查询参数工具类-部分代码如下：

/*** 查询参数*/
public class Query<T> extends LinkedHashMap<String, Object> {private static final long serialVersionUID = 1L;/*** mybatis-plus分页参数*/private Page<T> page;/*** 当前页码*/private int currPage = 1;/*** 每页条数*/private int limit = 10;public Query(JQPageInfo pageInfo) {//分页参数if(pageInfo.getPage()!= null){currPage = pageInfo.getPage();}if(pageInfo.getLimit()!= null){limit = pageInfo.getLimit();}//防止SQL注入（因为sidx、order是通过拼接SQL实现排序的，会有SQL注入风险）String sidx = SQLFilter.sqlInject(pageInfo.getSidx());String order = SQLFilter.sqlInject(pageInfo.getOrder());//mybatis-plus分页this.page = new Page<>(currPage, limit);//排序if(StringUtils.isNotBlank(sidx) && StringUtils.isNotBlank(order)){this.page.setOrderByField(sidx);this.page.setAsc("ASC".equalsIgnoreCase(order));}}public Query(Map<String, Object> params){this.putAll(params);//分页参数if(params.get("page") != null){currPage = Integer.parseInt((String)params.get("page"));}if(params.get("limit") != null){limit = Integer.parseInt((String)params.get("limit"));}this.put("offset", (currPage - 1) * limit);this.put("page", currPage);this.put("limit", limit);//防止SQL注入（因为sidx、order是通过拼接SQL实现排序的，会有SQL注入风险）String sidx = SQLFilter.sqlInject((String)params.get("sidx"));String order = SQLFilter.sqlInject((String)params.get("order"));this.put("sidx", sidx);this.put("order", order);//mybatis-plus分页this.page = new Page<>(currPage, limit);//排序if(StringUtils.isNotBlank(sidx) && StringUtils.isNotBlank(order)){this.page.setOrderByField(sidx);this.page.setAsc("ASC".equalsIgnoreCase(order));}}public Page<T> getPage() {return page;}public int getCurrPage() {return currPage;}public int getLimit() {return limit;}
}
