在使用 JAVA 开发Web应用程序的过程中，我们可能会用到不同的框架，在使用不同的框架组合进行开发的过程中，这些框架之间需要添加对应的配置文件，这里我们总结了一些开发中常见的配置方案.

1. Spring/SpringMVC/MyBatis

1.1 POM依赖配置

  1. <?xml version="1.0" encoding="UTF-8"?>
  3. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

1.2 配置数据源

  1. jdbc.url=jdbc:mysql://localhost:3306/数据库名称?zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8
  2. jdbc.username=root
  3. jdbc.password=123456
  4. jdbc.driver=com.mysql.cj.jdbc.Driver

在项目中添加 jdbc.properties 配置文件可以方便进行数据源的设置，如果在Spring配置文件中直接进行配置，对于链接地址中的 & 需要进行转义的处理，不推荐。

1.3 spring/mybatis 整合

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xmlns:aop="http://www.springframework.org/schema/aop"
  6.        xmlns:tx="http://www.springframework.org/schema/tx"
  7.        xsi:schemaLocation="http://www.springframework.org/schema/beans

  23.     </bean>
  25.     <!-- 事务处理 -->
  26.     <bean id="transactionManager" 
  27.         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  28.          <property name="dataSource" ref="dataSource" />
  29.     </bean>
  30.     <!-- 事务开启注解支持 -->
  31.     <tx:annotation-driven transaction-manager="transactionManager"/>
  33.     <!-- 开启注解扫描 -->
  34.     <context:component-scan base-package="注解扫描包">
  35.         <context:exclude-filter type="annotation" expression="排除扫描的包"/>
  36.     </context:component-scan>
  38.     <!-- 创建工厂对象 -->
  39.     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  40.         <property name="dataSource" ref="dataSource"></property>
  41.         <property name="mapperLocations" value="classpath:mybatis/mappers/*Mapper.xml"></property>
  42.     </bean>
  44.     <!-- 接口扫描器 -->

  46.         <property name="basePackage" value="DAO代码所在包"></property>
  47.     </bean>
  48. </beans>

在项目资源路径下添加 spring.xml 文件，其中包含数据源、事务处理、SQL映射文件地址等。

1.4 spring/springmvc 整合

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.     xmlns:context="http://www.springframework.org/schema/context"
  5.     xmlns:aop="http://www.springframework.org/schema/aop"

  11.         http://www.springframework.org/schema/aop 
  12.         https://www.springframework.org/schema/aop/spring-aop.xsd
  13.         http://www.springframework.org/schema/mvc
  14.         https://www.springframework.org/schema/mvc/spring-mvc.xsd">
  16.     <!-- 注解扫描 -->    
  17.     <context:component-scan base-package="控制层代码所在包" />
  19.     <!-- JSP 视图解析 -->
  20.     <bean id="jspviewResolver" 
  21.             class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  22.         <property name="prefix" value="/"/>
  23.         <property name="suffix" value=".jsp"/>
  24.     </bean>    
  26.     <mvc:annotation-driven>
  27.         <mvc:message-converters register-defaults="true">
  28.             <!-- json的解析 -->
  29.             <bean id="fastJsonHttpMessageConverter"
  30.                 class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
  31.                 <property name="supportedMediaTypes">
  32.                     <list>
  33.                         <value>application/json;charset=UTF-8</value>
  34.                     </list>
  35.                 </property>
  36.             </bean>
  37.         </mvc:message-converters>
  38.     </mvc:annotation-driven>
  39. </beans>

在项目中添加 springmvc.xml 配置文件夹，其中包含视图、JSON格式转换等。

1.5 Mybatis 配置

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE configuration
  3.   PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  4.   "http://mybatis.org/dtd/mybatis-3-config.dtd">
  5. <configuration>
  7.     <settings>
  8.         <setting name="logImpl" value="STDOUT_LOGGING"/>
  9.     </settings>
  11. </configuration>

首先，在项目资源路径下新建 mybatis 文件夹，创建 mybatis-config.xml 文件，设置SQL执行语句输出

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE mapper
  3.         PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  4.         "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  5. <mapper namespace="数据库处理接口(含包名)">
  7.     <!-- 预定义SQL语句 -->
  8.     <sql id="cols">
  9.         <!-- SQL列 -->
  10.     </sql>
  12.     <!-- 结果集映射，解决属性名和列名不一致的问题 -->
  13.     <resultMap id="唯一标识" type="实体类">
  14.         <id column="主键列名" property="属性名" />
  15.         <result column="列名" property="属性名"/>
  16.     </resultMap>
  18.     <!-- 添加信息 -->
  19.     <insert id="add" parameterType="实体类(含包名)">
  20.         INSERT INTO 表名 (列名1, 列名2, ……) VALUES (#{属性1}, #{属性1}, ……)
  21.     </insert>
  23.     <!-- 修改信息 -->
  24.     <update id="update" parameterType="实体类(含包名)">
  25.         UPDATE 表名
  26.         <trim prefix="SET" suffixOverrides=",">
  27.             <if test="属性 != null">
  28.                 列名 = #{属性},
  29.             </if>
  30.             <if test="属性 != null">
  31.                 列名 = #{属性}
  32.             </if>

  42.     <!-- 获取指定的ID信息 -->
  43.     <select id="qryOne" resultMap="结果集标识, 自定义的结果集">
  44.         SELECT <include refid="cols"></include>
  45.         FROM 表名
  46.         WHERE 主键列名 = #{属性}
  47.     </select>
  49.     <!-- 按条件模糊查询信息 -->
  50.     <select id="qryList"
  51.             resultMap="结果集标识, 自定义的结果集"
  52.             parameterType="实体类(含包名)">
  53.         SELECT <include refid="cols"></include>
  54.         FROM 表名
  55.         <where>
  56.             <if test="属性 != null and 属性 != ''">
  57.                 AND 列名 LIKE concat('%', #{属性}, '%')
  58.             </if>
  59.         </where>
  60.     </select>
  61. </mapper>

接下来，针对不同数据层接口，添加对应的SQL映射文件，在这里每个数据执行接口中对应的方法和对应的 SQL映射文件XML 节点中 id 的属性保持一致。

2.2 配置数据源

  1. jdbc.url=jdbc:mysql://localhost:3306/数据库名称?zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8
  2. jdbc.username=root
  3. jdbc.password=123456
  4. jdbc.driver=com.mysql.cj.jdbc.Driver

在项目中添加 jdbc.properties 配置文件可以方便进行数据源的设置，如果在Spring配置文件中直接进行配置，对于链接地址中的 & 需要进行转义的处理，不推荐。

3.2 系统核心配置

  1. server:
  2.    port: 系统端口
  3.    servlet:
  4.       context-path: /项目根路径
  5. spring:
  6.    http:
  7.        encoding:
  8.           force: true
  9.           charset: UTF-8
  10.           enabled: UTF-8
  11.    mvc:
  12.        static-path-pattern: /**
  13.    resources:
  14.        static-locations: classpath:/static/
  15.    devtools:
  16.        restart:
  17.           enabled: true  #设置开启热部署
  18.           additional-paths: src/main/java #重启目录
  19.    datasource:
  20.        username: root
  21.        password: 123456
  22.        url: jdbc:mysql://localhost:3306/数据库名称?zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8
  23.        driver-class-name: com.mysql.cj.jdbc.Driver
  24.        type: com.alibaba.druid.pool.DruidDataSource
  25.        initialSize: 5
  26.        minIdle: 5
  27.        maxWait: 60000
  28.    thymeleaf:
  29.        prefix: classpath:/static/
  30.        suffix: .html
  31. mybatis:
  32.    config-location: classpath:mybatis/mybatis-config.xml
  33.    mapper-locations: classpath:mybatis/mappers/*.xml
  34. pagehelper:
  35.    helperDialect: mysql

在项目下新建 application.yml 文件，其中添加如下的设置，这里包含项目运行端口、项目根路径、数据库连接、静态资源路径等常见内容。

3.3 mybatis 配置

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE configuration
  3.   PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  4.   "http://mybatis.org/dtd/mybatis-3-config.dtd">
  5. <configuration>
  7.     <settings>
  8.         <setting name="logImpl" value="STDOUT_LOGGING"/>
  9.     </settings>
  11. </configuration>

首先，在项目资源路径下新建 mybatis 文件夹，创建 mybatis-config.xml 文件，设置SQL执行语句输出

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE mapper
  3.         PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  4.         "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  5. <mapper namespace="数据库处理接口(含包名)">
  7.     <!-- 预定义SQL语句 -->
  8.     <sql id="cols">
  9.         <!-- SQL列 -->
  10.     </sql>
  12.     <!-- 结果集映射，解决属性名和列名不一致的问题 -->
  13.     <resultMap id="唯一标识" type="实体类">
  14.         <id column="主键列名" property="属性名" />
  15.         <result column="列名" property="属性名"/>
  16.     </resultMap>
  18.     <!-- 添加信息 -->
  19.     <insert id="add" parameterType="实体类(含包名)">
  20.         INSERT INTO 表名 (列名1, 列名2, ……) VALUES (#{属性1}, #{属性1}, ……)
  21.     </insert>
  23.     <!-- 修改信息 -->
  24.     <update id="update" parameterType="实体类(含包名)">
  25.         UPDATE 表名
  26.         <trim prefix="SET" suffixOverrides=",">
  27.             <if test="属性 != null">
  28.                 列名 = #{属性},
  29.             </if>
  30.             <if test="属性 != null">
  31.                 列名 = #{属性}
  32.             </if>
  33.         </trim>
  34.         WHERE 主键列名 = #{属性}
  35.     </update>
  37.     <!-- 删除信息 -->
  38.     <delete id="delete" parameterType="实体类(含包名)">
  39.         DELETE FROM 表名 WHERE 列名 = #{属性}
  40.     </delete>
  42.     <!-- 获取指定的ID信息 -->
  43.     <select id="qryOne" resultMap="结果集标识, 自定义的结果集">
  44.         SELECT <include refid="cols"></include>
  45.         FROM 表名
  46.         WHERE 主键列名 = #{属性}
  47.     </select>
  49.     <!-- 按条件模糊查询信息 -->
  50.     <select id="qryList"
  51.             resultMap="结果集标识, 自定义的结果集"
  52.             parameterType="实体类(含包名)">
  53.         SELECT <include refid="cols"></include>
  54.         FROM 表名
  55.         <where>
  56.             <if test="属性 != null and 属性 != ''">
  57.                 AND 列名 LIKE concat('%', #{属性}, '%')
  58.             </if>
  59.         </where>
  60.     </select>
  61. </mapper>

接下来，针对不同数据层接口，添加对应的SQL映射文件，在这里每个数据执行接口中对应的方法和对应的 SQL映射文件XML 节点中 id 的属性保持一致。
