maven中spring+springmvc+mybatis整合详细配置

首先配置mybatis，可以参考这篇博客的前期基础配置使用。

下面配置结构：

 需要的jar，在pom.xml中引入

下面是applicationContext.xml配置，连接数据库事务的配置

</beans>

 对应的jdbc.properties配置，如果出现以下错误

spring连接c3p0出现错误 Connections could not be acquired from the underlying database!

可以查看这篇博客解决方案

https://blog.csdn.net/qq_41520636/article/details/84344133

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/stus?useUnicode=true&characterEncoding=utf8&useSSL=false
jdbc.username=root
jdbc.password=123
#最大连接数
maxPoolSize=100
#最小连接数
minPoolSize=20
# 关闭连接后不自动commit
autoCommitOnClose=false
# 获取连接超时时间
checkoutTimeout=10000
# 初始化连接
initialSize=30
#driver default 指定由连接池所创建的连接的只读（read-only）状态。
#如果没有设置该值，则“setReadOnly”方法将不被调用。（某些驱动并不支持只读模式，如：Informix）
defaultReadOnly=
#driver default 指定由连接池所创建的连接的事务级别（TransactionIsolation）。
#可用值为下列之一：（详情可见javadoc。）NONE,READ_UNCOMMITTED, READ_COMMITTED, REPEATABLE_READ, SERIALIZABLE
defaultTransactionIsolation=READ_UNCOMMITTED
#连接数
acquireIncrement=30

在然后是mybatis-config.xml配置

<?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>
    <!-- 配置全局属性 -->
    <settings>
        <!--允许返回多个结果集-->
        <setting name="multipleResultSetsEnabled" value="true"></setting>
        <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 -->
        <setting name="useGeneratedKeys" value="true" />
        <!-- 使用列别名替换列名 默认:true -->
        <setting name="useColumnLabel" value="true" />
        <!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} -->
        <setting name="mapUnderscoreToCamelCase" value="true" />
        <!--二级缓存开关-->
        <setting name="cacheEnabled" value="true"></setting>
        <!--允许返回多个结果集-->
        <setting name="multipleResultSetsEnabled" value="true"></setting>
        <!--日志-->
        <setting name="logImpl" value="LOG4J"></setting>
        <!-- 延迟加载总开关 -->
        <setting name="lazyLoadingEnabled" value="false"/>
        <!-- 侵入懒加载，设置为false则按需加载，否则会全部加载 -->
        <setting name="aggressiveLazyLoading" value="false"/>
        <!--设置一个时限，以决定让驱动器等待数据库回应的多长时间为超时-->
        <setting name="defaultStatementTimeout" value="25000" />
    </settings>
    <!-- mybatis分页插件 -->
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>
    </plugins>
</configuration>

接着是log4j.properties的配置

#---- global logging configuration
#---- level: FATAL,ERROR,WARN,INFO,DEBUG
#---- appender: console, file, mail
### set log levels ###
log4j.rootLogger = DEBUG,console

### 输出到控制台 ###
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.console.Target = System.out
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern =  %d{yyyy-MM-dd HH\:mm\:ss} %5p %c{1}:%L - %m%n

### 输出到日志文件 ###
log4j.appender.file = org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File = ${webapp.root}/WEB-INF/logs/platform.log
log4j.appender.file.DatePattern=_yyyyMMdd'.log'
#log4j.appender.file.Append = true
#log4j.appender.file.Threshold = INFO
log4j.appender.file.layout = org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern =%-d{yyyy-MM-dd HH\:mm\:ss}  [ %t\:%r ] - [ %p ]  %m%n

### 打印SQL ###
#log4j.logger.com.ibatis=DEBUG
#log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
#log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
#log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.java.sql.ResultSet=DEBUG

最后是spring-mvc.xml配置

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:annotation-config/>

    <!-- 开启注解( 用于将对象转换为 JSON) -->

    <!--处理静态资源-->
