Is Mybatis supported with Spring 4.x?

由 安稳与你 提交于 2019-12-10 19:39:27
问题 I tried mybatis-spring 1.2.2 with mybatis 3.2.5 and Spring version 4.1.0.Release and it appears like it is not supported. mybatis-spring 1.2.2 spring contains org.springframework.core.MethodParameter class however, getContainingClass() is not present. I am getting the exception: java.lang.NoSuchMethodError: org.springframework.core.MethodParameter.getContainingClass() Any idea is I could use Mybatis with Spring 4x at all? (even ibatis seems to be unsupported) 回答1: Looking in the pom.xml of

1 .insert,update,delete 返回值 ( 1 ).insert 返回的为插入的主键值，但必须在配置文件中加入 < selectKey /> 如果主键值为String < selectKey resultClass = " string " keyProperty = " id " > SELECT @@IDENTITY AS ID </ selectKey > 如果主键值为Int型 < selectKey resultClass = " java.lang.Integer " keyProperty = " id " > SELECT @@IDENTITY AS ID </ selectKey > 或者 < selectKey resultClass = " int " keyProperty = " id " > SELECT @@IDENTITY AS ID </ selectKey > 注：@@IDENTITY只是SQL Server的写法，其他数据库也有相关的属性。 ( 2 ).Update,和Delete返回为修改数据影响的条数； 2 .SQL模糊查询的两种方法 ( 1 ).如果是模糊查询，在关键字传入前加‘％’； 例：String keyword = ” % ” + keyword + ” % ”; ( 2 ).配置文件的写法： select name

MyBatis使用自定义TypeHandler转换类型

由 我怕爱的太早我们不能终老 提交于 2019-12-10 03:28:29
MyBatis虽然有很好的SQL执行性能，但毕竟不是完整的ORM框架，不同的数据库之间SQL执行还是有差异。 笔者最近在升级 Oracle 驱动至 ojdbc 7 ，就发现了处理DATE类型存在问题。还好MyBatis提供了使用自定义TypeHandler转换类型的功能。 本文介绍如下使用 TypeHandler 实现日期类型的转换。 问题背景 项目中有如下的字段，是采用的DATE类型： birthday = #{birthday, jdbcType=DATE}, 在更新 Oracle 驱动之前，DateOnlyTypeHandler会做出处理，将 jdbcType 是 DATE 的数据转为短日期格式（‘年月日’）插入数据库。毕竟是生日嘛，只需要精确到年月日即可。 但是，升级 Oracle 驱动至 ojdbc 7 ，就发现了处理DATE类型存在问题。插入的数据格式变成了长日期格式（‘年月日时分秒’），显然不符合需求了。 解决方案： MyBatis提供了使用自定义TypeHandler转换类型的功能。可以自己写个TypeHandler来对 DATE 类型做特殊处理： /** * Welcome to https://waylau.com */ package com.waylau.lite.mall.type; import java.sql.CallableStatement;

Can MyBatis create the database schema?

由 雨燕双飞 提交于 2019-12-09 16:43:18
问题 Has MyBatis any feature to allow create the SQL schema from de Class Model like Hibernate does? I'm looking for that in Google and I only found information about MyBatis Generator (http://mybatis.github.io/generator/). This tool seems to be useful for generate the Java model from the SQL Schema, which is just the opposite I want. 回答1: Can MyBatis create the database schema? I'm afraid not. In order to do that you need an ORM and MyBatis is not an ORM. With an ORM solution (like Hibernate for

Inserting child objects in MyBatis

问题 I have a very simple object graph that I want to store in a database using MyBatis. If I make a brand new object graph (a BatisNode with two details), how do I write code to be sure the child objects are created? Here are the details: public class BatisNode { protected int id; protected List details; protected String name; //Constructor and getters. } public class BatisNodeDetail { protected int id; protected BatisNode parent; protected String name; //Constructor and getters. } Schema: CREATE

API安全之授权 访问控制： 1，ACL ：Access Control Lists，直接给每个用户授权，他能访问什么。开发简单，但是用户多的话，给每个用户授权比较麻烦。 2，RBAC：Role Based Access Control。给角色授权，给用户赋予角色。授权简单，开发麻烦。 下边用ACL来实现简单的权限控制，在用户表里加入permission字段标识权限。 项目代码结构： 数据库，User表： 插入两条数据 User类： /** * <p> * User * </p> * * @author 李浩洋 * @since 2019-10-26 */ @Data public class User implements Serializable { private static final long serialVersionUID = 1L; private Long id; private String name; private String username; private String password; private String permissions; public boolean hasPermission(String method){ boolean result = false; if(StringUtils.equalsIgnoreCase(

Auto-incrementation with HSQLDB (2.2.8) + DDLUtils

由 我只是一个虾纸丫 提交于 2019-12-08 06:35:49
问题 I want to use HSQLDB as an embedded database but am having trouble getting it to auto-increment . As far as I understand, [CALL] IDENTITY() can be used to get the last primary key value. However, experiments through both iBatis and HSQLDB's DatabaseManagerSwing continually return a 0 value. How can I get auto-incrementation to work with HSQLDB? Edit: I didn't mention that I'm using DDLUtils to autogenerate tables. The following does not suit HSQLDB: <?xml version="1.0"?> <!DOCTYPE database
