This series is a record and share of the course "Java Mainstream Technology Stack SSM+SpringBoot Shop System".
1. Why learn java
Now it's the front end, I've always wanted to be a full stack, I've learned background languages like node and python, and I've written a few small projects like egg Django that can also be used, but I find that I can't get started with the system, plus I don't feel that the code I write is particularly good, and I can't use object-oriented language very well.To learn java.It is also helpful for typescript on the next step.
2. Plan (to be completed in different languages for the same project)
1. I plan to do three different languages in the background: java, node, python
2. If you need to do 4 different frameworks: vue, react, react-native, angular
3. Project Configuration
1. Complete Folders
2. Remaining configurations
1. Create jdbc.properties
//Directory src/main/resources/jdbc.properties jdbc.driver=com.mysql.cj.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/javao2o?userUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=pp123456
2. Create mybatis-config.xml
// src/main/resources/mybatis-config.xml <?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> <!-- Configure Global Properties --> <settings> <!-- Use jdbc Of getGeneratedKeys Get Database Self-Increasing Primary Key Value --> <setting name="useGeneratedKeys" value="true" /> <!-- Replace column alias default with column labels:true --> <setting name="useColumnLabel" value="true" /> <!-- Turn on hump naming conversion:Table{create_time} -> Entity{createTime} --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> </configuration>
3. Create spring-dao.xml
//src/main/resources/spring/spring-dao.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--Configuration Integration mybatis process--> <!--1:Configure database related parameters--> <context:property-placeholder location="classpath:jdbc.properties"/> <!--2.Database Connection Pool--> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!--Configure Connection Pool Properties--> <property name="driverClass" value="${jdbc.driver}"/> <property name="jdbcUrl" value="${jdbc.url}"/> <property name="user" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <!--c3p0 Private properties of connection pools--> <property name="maxPoolSize" value="30"/> <property name="minPoolSize" value="10"/> <!--Close connection not automatically commit--> <property name="autoCommitOnClose" value="false"/> <!--Get connection timeout--> <property name="checkoutTimeout" value="3000"/> <!--Number of retries when getting links fails--> <property name="acquireRetryAttempts" value="2"/> </bean> <!--3.To configure SqlSessionFactory object--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!--Inject database connection pool--> <property name="dataSource" ref="dataSource"/> <!--To configure mybatis Global Profile--> <property name="configLocation" value="classpath:mybatis-config.xml"/> <!--scanning entity Packages use aliases to simplify writing multiple packages;Separate--> <property name="typeAliasesPackage" value="wang.beastxw.javao2o.entity"/> <!--scanning sql configuration file:mapper Needed xml file--> <property name="mapperLocations" value="classpath:mapper/*.xml"/> </bean> <!--4.Configuration Scan Dao Interface packages, dynamic implementation dao Interface, injected into spring In container--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--injection sqlSessionFactory--> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <!--Give needed scan dao Interface Package--> <property name="basePackage" value="wang.beastxw.javao2o.dao"/> </bean> </beans>
4. Create spring-service.xml
// src/main/resources/spring/spring-service.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- scanning service All types of notes used under the package --> <context:component-scan base-package="wang.beastxw.javao2o.service" /> <!-- Configure Transaction Manager --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- Inject database connection pool --> <property name="dataSource" ref="dataSource" /> </bean> <!-- Configuring annotation-based declarative transactions --> <tx:annotation-driven transaction-manager="transactionManager" /> </beans>
5. Create spring-web.xml
// src/main/resources/spring/spring-web.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <!-- To configure SpringMVC --> <!-- 1.open SpringMVC Annotation mode --> <mvc:annotation-driven /> <!-- 2.Static Resource Default servlet To configure (1)Join the processing of static resources: js,gif,png (2)Allow use"/"Map as a whole --> <mvc:resources mapping="/resources/**" location="/resources/" /> <mvc:default-servlet-handler /> <!-- 3.Define View Parser --> <!-- No need jsp，Returns data from the result, so is.html --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/html/"></property> <property name="suffix" value=".html"></property> </bean> <!-- 4.scanning web Dependent bean --> <context:component-scan base-package="wang.beastxw.javao2o.web" /> </beans>
6. Modify web.xml
// Modify web.xml <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> <display-name>Archetype Created Web Application</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>spring-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-*.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>spring-dispatcher</servlet-name> <!-- Match all requests by default --> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
