mybatis對象化封裝，去XML，去SQL編寫，提供CRUD操作

mybatis-util

簡介

• mybatis-util是爲了簡化mybatis開發過程中的sql.xml的開發和維護；
• 去XML，SQL開發和維護；
• 本項目支持Bean對象註解，已達到增刪查改的業務需求；
• 本項目是spring boot結構
• insert:支持自增ID；
• update:以ID爲查詢條件修改非主鍵字段數據；
• 查詢當前支持 =，!=，IN，右模糊查詢（like 'aa%‘），>，>=，<，<=查詢條件；
• 查詢支持查詢結果和Bean自動轉換
• 支持數據轉換事件，當前數據結構只支持string（例如：屬性json數據和對象轉換）；
• 支持排序分頁（支持limit max,offset min校驗）
• 支持簡單類型結果查詢（List&lt;String&gt;，List&lt;Long&gt;，List&lt;Integer&gt;，List&lt;Double&gt;)
• 支持對象查詢（並支持屬性註解）
• 本項目當前支持單表操作
• 本項目當前只支持MySql數據庫

示例

可以查看：mybatis-util-example

/** 實體對象 */
@TableName(name="test")
public class TestBean {
	@GeneratedValue
	private Integer id;
	private String name;
	private String testName;
	private Date createTime;
	
	@FieldAnalyzeHandler(handler = PersonFieldAnalyzeHandler.class)
	private Person person;

 

/** 數據轉換實例 */
public class PersonFieldAnalyzeHandler implements AbstractFieldAnalyzeHandler<Person>{

	@Override
	public Person handler(Object obj) {
		if(obj == null || "".equals(obj)) {
			return null;
		}
		Gson gson = new Gson();
		return gson.fromJson(obj.toString(), Person.class);
	}

	@Override
	public String rehandler(Object obj) {
		if(obj == null) {
			return null;
		}
		return new Gson().toJson(obj);
