jdbc，hibernate，mybatis的区别

对于jdbc和hibernate以及mybatis的主要区别的分析

怎么理解Spring JDBC，MyBatis 都是基于数据源的Connection访问数据库，Hibernate就不是吗？

我这句话是Spring 3.0就是那么简单上说的，意思是Spring为SpringJDBC和MyBatis提供了相同的事务管理器实现类，而单独为Hibernate3.0实现了一个，是因为他们的使用形式不同

hibernate4 无法连接postgreSQL数据库

项目中要使用postgreSQL，之前用的mysql是可以连接的，但是切换到postgreSQL后，tomcat加载时就直接在： 2014-08-26 20:26:52 [localhost-startStop-1] DEBUG org.hibernate.engine.jdbc.internal.JdbcServicesImpl - Database -> name : PostgreSQL version : 9.3.1.3 major : 9 minor : 3 2014-08-26 20:26:52 [localhost-startStop-1] DEBUG org.hibernate.engine.jdbc.internal.JdbcServicesImpl - Driver -> name : PostgreSQL Native Driver version : PostgreSQL 9.3 JDBC4.1 (build 1102) major : 9 minor : 3 2014-08-26 20:26:52 [localhost-startStop-1] DEBUG org.hibernate.engine.jdbc.internal.JdbcServicesImpl - JDBC version : 4.0 这儿等待，也不报错，就是不往下执行。如果切换为mysql又可以正常启动，而且可以用mybatis连接postgreSQL数据，数据源配置都一样。 配置文件： <!-- 数据源datasource --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="org.postgresql.Driver"> </property> <property name="url" value="url"> </property> <property name="username" value="tapi"></property> <property name="password" value="123456"></property> </bean> <!--创建Spring的SessionFactory工厂 --> <!--和hibernate4整合没有提供专门的针对Annotation的类，直接在LocalSessionFactoryBean中已经集成--> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 注入数据源 --> <property name="dataSource" ref="dataSource" /> <!-- 设置Spring去哪个包中查找相应的实体类 --> <property name="packagesToScan"> <list> <value>com.travelsky.tapiweb.eterm.model</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.connection.autocommit">true</prop> <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop> <prop key="hibernate.show_sql">false</prop> <prop key="hibernate.format_sql">false</prop> </props> </property> </bean> 如果改成这样，其他地方不变动： <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"> </property> <property name="url" value="url"> </property> <property name="username" value="tapi"></property> <property name="password" value="123456"></property> </bean> 又可以连接并且正常启动，hibernate版本为4.2.0final，postgreSQL驱动jdbc4和jdbc4.1都不能成功，jkd版本是1.6，求大神解决下啊，纠结一天了

springBoot整合mybatis时的错，求助！

Make sure your own configuration does not rely on that class.

gradle+spring boot+mybatis+PageHelper 分页无效

被折磨了一天，网上也找了很多解决办法，都不行，求助大神 如果PageHelper 降版本到4.0的话，PageInfo里的属性就全是空的， 直接用PageHelper.startPage(1, 2); 也没用。 ，不废话，直接上代码。 测试类： ``` @RunWith(SpringRunner.class) @SpringBootTest public class UserMappertest { @Autowired private UserMapper userMapper; @Test public void getAllByPage(){ Map<String,Object> map = new HashMap<String,Object>(); map.put("email", "a"); // map.put("id", "2"); PageHelper.startPage(1, 2,true);// 默认从第一页开始，每页五条 List<Map<String,Object>> users = userMapper.getAllByPage(map); PageInfo<Map<String,Object>> pageBlog = new PageInfo<Map<String,Object>>(users);// 将查出来的blogArticleList绑定到pageInfo中 System.out.println(">======page====>"+pageBlog.toString()); int a = 1; for(Map<String,Object> m:users) { System.out.println(">============users===a====>"+a); System.out.println(">============users===username====>"+m.get("username")); a++; } } } ``` 输出结果： ``` >======page====>PageInfo{pageNum=1, pageSize=7, size=7, startRow=0, endRow=6, total=7, pages=1, list=[{password=$76NoUnuTJ8iAtKIUi, name=qweq,id=1, avatar=//localhost:8081/view/5a9f9509c99a7138a8ea306c, email=i@om, username=admin}, {password=$2a$IUi, name=Wu, id=2, avatar=//localhost:8081/view/5a9f962ec99a7138a8ea306d, email=wa@wa.com, username=wau}, {password=$2a$1O7s3Jo4XW, name=是释放, id=3, avatar=//localhost:8081/view/5a9f9684c99a7138a8ea306e, email=12321@sfa.cn, username=wjy0703}, {password=123456, name=fs士大夫撒, id=4, avatar=//localhost:8081/view/5aa777c3c99a715b60793591, email=safdaf@ssfdsa.com, username=wjy}, {password=$2EXdOSDS, name=发大好时光, id=6, avatar=//localhost:8081/view/5aa77a8cc99a715b60793592, email=123212@sfa.cn, username=wjiyu}, {password=123456, name=搭顺风很舒服, id=7, email=safdafaaa@ssfdsa.com, username=qwe123}, {password=$2QB6cdbsAySst80C9FS, name=safddasfa, id=9, email=fas2f@sfa.com, username=abc123}], prePage=0, nextPage=0, isFirstPage=true, isLastPage=true, hasPreviousPage=false, hasNextPage=false, navigatePages=8, navigateFirstPage=1, navigateLastPage=1, navigatepageNums=[1]} >============users===a====>1 >============users===username====>admin >============users===a====>2 >============users===username====>waylau >============users===a====>3 >============users===username====>wjy0703 >============users===a====>4 >============users===username====>wjy >============users===a====>5 >============users===username====>wayu >============users===a====>6 >============users===username====>qwe123 >============users===a====>7 >============users===username====>abc123 ``` gradle配置 springBootVersion = '1.5.2.RELEASE'： ``` // 添加 MySQL连接驱动 的依赖 compile('mysql:mysql-connector-java:6.0.5') // 添加 Apache Commons Lang 依赖 compile('org.apache.commons:commons-lang3:3.5') //mybatis依赖 compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.0') //pagehelper依赖 compile('com.github.pagehelper:pagehelper:5.1.2') ``` mybatis-config.xml 配置： 下面使用"com.github.pagehelper.PageHelper"也不行，都不报错，也不能分页。 ``` <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <typeAliases> <typeAlias alias="Integer" type="java.lang.Integer" /> <typeAlias alias="Long" type="java.lang.Long" /> <typeAlias alias="HashMap" type="java.util.HashMap" /> <typeAlias alias="LinkedHashMap" type="java.util.LinkedHashMap" /> <typeAlias alias="ArrayList" type="java.util.ArrayList" /> <typeAlias alias="LinkedList" type="java.util.LinkedList" /> </typeAliases> <plugins> <plugin interceptor="com.github.pagehelper.PageInterceptor"> </plugin> </plugins> </configuration> ``` application.properties 配置： ``` #Thymeleaf spring.thymeleaf.encoding=UTF-8 #热部署静态文件 spring.thymeleaf.cache=false #使用HTML5标准 spring.thymeleaf.mode=HTML5 #DataSource spring.datasource.url=jdbc:mysql://localhost/boot?useSSL=false&serverTimezone=UTC&characterEncoding=utf-8 spring.datasource.username=boot spring.datasource.password=boot spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver # mybatis配置 mybatis.config-location=classpath:mybatis-config.xml // 配置文件位置 mybatis.typeAliasesPackage=com.educate.domain mybatis.mapper-locations=classpath:com/educate/mapper/**/*.xml mybatis.config-locations=classpath:mybatis/mybatis-config.xml #pagehelper分页插件配置 pagehelper.helperDialect=mysql pagehelper.reasonable=true pagehelper.supportMethodsArguments=true #JPA spring.jpa.show-sql=true spring.jpa.hibernate.ddl-auto=update ``` UserMapper.xml 配置： ``` <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="com.educate.mapper.user.UserMapper" > <sql id="Base_Column_List" > id,name, username, password, email,avatar </sql> <sql id="Base_Column_Where" > where 1=1 <if test="id != null"> and id=#{id}</if> <if test="name != null"> and name like '%${name}%'</if> <if test="email != null"> and email like '%${email}%'</if> </sql> <select id="getAll" resultType="java.util.HashMap" parameterType="java.util.HashMap"> SELECT <include refid="Base_Column_List" /> FROM user <include refid="Base_Column_Where" /> </select> <select id="getAllByPage" resultType="java.util.HashMap"> SELECT <include refid="Base_Column_List" /> FROM user <include refid="Base_Column_Where" /> </select> </mapper> ``` UserMapper 代码： ``` @Mapper public interface UserMapper { List<Map<String,Object>> getAll(Map<String,Object> map);

刚培训出来的小白明天入职，求教一些公司实操的细节问题，免得明天被耻笑

1，明天入职公司的数据库是mysql，我在培训班的时候，写连接数据库的db.properties都是这么写的：  我想知道，公司里的数据库账号，密码也是自己去设，还是有一个公用的啊？另外jdbc.url这行，培训时我一直写的是localhost：3306或者///代表本机，到了公司不能写本机地址了对不对？如果是的话应该写什么 2，面试时，公司人说我去了要负责一款新APP的分析，这个分析，具体要做什么？我的理解就是分析这个APP的功能，需要建立哪些模型（比如User），模型里面有什么属性（比如username），需要用到什么框架实现功能，其他还需要做什么呢？ 3，开发APP，我之前学的Mybatis，hibernate，Spring，struts2框架也适用吧？MVC结构也适用吗？一样可以分表现层，持久层，服务层对吧？

mybatis配置问题（应该是路径问题）

Mybatis + SpringData-Jpa 事物提交问题

springboot项目启动问题

 如图 数据库连接设置为本地就启动不起来 停在这里 换为阿里云就启动正常 什么情况 下面这个图片是连接换成阿里云后启动正常  以下是数据库配置： spring.application.name = xmzjcqgl server.port = 8529 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://39.98.209.181:3306/history_as10_order?useUnicode=true&characterEncoding=UTF-8 spring.datasource.username=dog spring.datasource.password=riskdev #spring.datasource.url=jdbc:mysql://localhost:3306/history_as10_order?seSSL=true #spring.datasource.username=root #spring.datasource.password=root #spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver #spring.jpa.properties.hibernate.hbm2ddl.auto=update mybatis.type-aliases-package=com.example.xmzjcqgl.model mybatis.mapper-locations=classpath:mybatis/*.xml maxHttpHeaderSize="1" #编码格式 charset=UTF-8

No provider available from registry ip for service com.zys.store.service.api.HelloServiceApi:1.0.0 on consumer ip use dubbo version 2.6.2

springboot整合zookeeper和dubbo报错 linux上zk版本号是3.4.14 项目用的zk包是3.4.9 dubbo用的是2.6.2 springboot是2.1.6 用main方式先运行store的模块 再运行order的模块 这个时候用浏览器去访问http://localhost:8088/hello?name=zys这个时候控制台就报错No provider available from registry 启动的时候不报错 浏览器访问就报错了 看zk日志有说是HelloServiceApi这个类的节点已经存在 但是我觉得跟这个问题不大 因为运行一次就会创建一个节点 多次的话肯定报节点存在的错 我的linux是虚拟机 并且已经关闭了防火墙 不存在端口跑不通的情况 1. 项目架构是maven的聚合项目 2. 在zys-store-api写接口 package com.zys.store.service.api; public interface HelloServiceApi { String sayHello(String name); } 3.在zys-store暴露接口 package com.zys.store.service.provider; import com.alibaba.dubbo.config.annotation.Service; import com.zys.store.service.api.HelloServiceApi; @Service( version = "1.0.0", application = "zys-store", protocol = "dubbo", registry = "zys-store-registry" ) public class HelloServiceProvider implements HelloServiceApi{ @Override public String sayHello(String name) { return "hello" + name; } } 下面是zys-store的yml的配置 dubbo: application: id: zys-store name: zys-store qos-port: 22212 qos-enable: true scan: base-packages: com.zys.store.* protocol: id: dubbo name: dubbo port: 12343 registry: id: zys-store-registry address: zookeeper://192.168.146.132:2181?backup=192.168.146.131:2181,192.168.146.133:2181 4.在zys-order调用接口 package com.zys.order.controller; import com.alibaba.dubbo.config.annotation.Reference; import com.zys.store.service.api.HelloServiceApi; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import javax.annotation.Resource; @RestController public class HelloController { @Reference( version = "1.0.0", application = "zys-order", interfaceName = "com.zys.store.service.api.HelloServiceApi", check = false, timeout = 3000, retries = 0 //读请求3次 写请求不重复 ) private HelloServiceApi helloServiceApi; @RequestMapping("/hello") public String hello(@RequestParam("name") String name){ return helloServiceApi.sayHello(name); } } 下面是zys-order的yml的配置 ```dubbo: application: id: zys-order name: zys-order qos-port: 22211 qos-enable: true qos-accept-foreign-ip: false scan: base-packages: com.zys.order.* protocol: id: dubbo name: dubbo port: 12343 registry: id: zys-order-registry address: zookeeper://192.168.146.132:2181?backup=192.168.146.131:2181,192.168.146.133:2181 store端的启动日志 2019-11-20 10:18:35.426 INFO 50632 --- [ main] a.b.d.c.e.WelcomeLogoApplicationListener : :: Dubbo Spring Boot (v0.2.0) : https://github.com/apache/incubator-dubbo-spring-boot-project :: Dubbo (v2.6.2) : https://github.com/apache/incubator-dubbo :: Google group : dev@dubbo.incubator.apache.org 2019-11-20 10:18:35.430 INFO 50632 --- [ main] e.OverrideDubboConfigApplicationListener : Dubbo Config was overridden by externalized configuration {dubbo.application.id=zys-store, dubbo.application.name=zys-store, dubbo.application.qos-enable=true, dubbo.application.qos-port=22212, dubbo.protocol.id=dubbo, dubbo.protocol.name=dubbo, dubbo.protocol.port=12343, dubbo.registry.address=zookeeper://192.168.146.132:2181?backup=192.168.146.131:2181,192.168.146.133:2181, dubbo.registry.id=zys-store-registry, dubbo.scan.base-packages=com.zys.store.*} . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.1.6.RELEASE) 2019-11-20 10:18:35.488 INFO 50632 --- [ main] com.zys.store.ZysStoreApplication : Starting ZysStoreApplication on DESKTOP-O0S84K8 with PID 50632 (D:\ideaworkspace\zys-project\zys-store\target\classes started by Administrator in D:\ideaworkspace\zys-project) 2019-11-20 10:18:35.489 INFO 50632 --- [ main] com.zys.store.ZysStoreApplication : No active profile set, falling back to default profiles: default 2019-11-20 10:18:35.963 WARN 50632 --- [ main] o.m.s.mapper.ClassPathMapperScanner : No MyBatis mapper was found in '[com.zys.store.dao, com.zys.store.mapper]' package.

一、什么是比特币 比特币是一种电子货币，是一种基于密码学的货币，在2008年11月1日由中本聪发表比特币白皮书，文中提出了一种去中心化的电子记账系统，我们平时的电子现金是银行来记账，因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述，这一层面介绍的文章很多，本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人

程序员接私活怎样防止做完了不给钱？

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。 那么，怎么保证自己的薪酬安全呢？ 我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

程序员：我终于知道post和get的区别

IT界知名的程序员曾说：对于那些月薪三万以下，自称IT工程师的码农们，其实我们从来没有把他们归为我们IT工程师的队伍。他们虽然总是以IT工程师自居，但只是他们一厢情愿罢了。 此话一出，不知激起了多少(码农)程序员的愤怒，却又无可奈何，于是码农问程序员。 码农：你知道get和post请求到底有什么区别？ 程序员：你看这篇就知道了。 码农：你月薪三万了？ 程序员：嗯。 码农：你是怎么做到的? 程序员：
