IntelliJ IDEA整合SSM框架
阿新 • • 發佈:2019-02-09
SSM框架整合(IntelliJ IDEA + maven + Spring + SpringMVC + MyBatis)
1. 建立maven專案
1.1 File–>New Module,進入建立專案視窗
1.2 點選Next,填寫GroupId、ArtifactId和Version
1.3 在Properties中新增一個引數 archetypeCatalog=internal,不加這個引數,在maven生成骨架的時候將會非常慢,有時候直接卡住。
1.4 填寫Module name
1.5 生成maven的專案骨架之後,我們還需要手動在 src/main 下建立 java目錄。完整的專案結構如下圖
1.6 這裡的目錄建好之後還需要設定一下,讓idea識別目錄作用,選擇File-Project Structure
到此為止,專案的框架基本搭建完成
2. 專案配置檔案
2.1 這裡使用maven來引入專案所需要的jar包,所以也就不需要手動來管理jar包了
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.web</groupId> <artifactId>ssm</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>ssm Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- 設定專案編碼編碼 --> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <!-- spring版本號 --> <spring.version>4.3.5.RELEASE</spring.version> <!-- mybatis版本號 --> <mybatis.version>3.4.1</mybatis.version> </properties> <dependencies> <!-- java ee --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency> <!-- 單元測試 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!-- 實現slf4j介面並整合 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.2</version> </dependency> <!-- JSON --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.7</version> </dependency> <!-- 資料庫 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.41</version> <scope>runtime</scope> </dependency> <!-- 資料庫連線池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!-- MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring整合包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> </dependencies> <build> <finalName>ssm</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <!-- 設定JDK版本 --> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
2.2 這裡可以控制輸出格式和內容,有興趣的可以自己設定
logback.xml
<?xml version="1.0" encoding="UTF-8"?> <configuration debug="true"> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> <root level="debug"> <appender-ref ref="STDOUT"/> </root> </configuration>
2.3 新建jdbc.properties檔案
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
#資料庫地址
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8&useSSL=false
#使用者名稱
jdbc.username=root
#密碼
jdbc.password=201314
#最大連線數
c3p0.maxPoolSize=30
#最小連線數
c3p0.minPoolSize=10
#關閉連線後不自動commit
c3p0.autoCommitOnClose=false
#獲取連線超時時間
c3p0.checkoutTimeout=10000
#當獲取連線失敗重試次數
c3p0.acquireRetryAttempts=2
2.4 新建log4j配置檔案
log4j.properties
log4j.rootLogger=INFO,Console,File
#控制檯日誌
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=[%p][%t][%d{yyyy-MM-dd HH:mm:ss}][%C] - %m%n
#普通檔案日誌
log4j.appender.File=org.apache.log4j.RollingFileAppender
log4j.appender.File.File=logs/ssm.log
log4j.appender.File.MaxFileSize=10MB
#輸出日誌,如果換成DEBUG表示輸出DEBUG以上級別日誌
log4j.appender.File.Threshold=ALL
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH:mm:ss}][%C] - %m%n
2.5 新建spring和mybatis整合所需的配置檔案
