【Maven+SSM+Druid】IDEA中使用maven搭建 ssm+druid

目录

• 一、使用IDEA创建maven项目
  • • 1.首先选择 File => New Project ,选择创建maven项目，勾选webapp骨架（使用骨架创建项目帮我们事先构建好web结构）
    • 2.接下来按照图片选择并创建maven项目
    • 3.创建成功后的项目结构展示
• 二、向pom文件中导入相关jar包坐标
• 三、添加ssm和druid所需配置文件
  • • 1.db.properties
    • 2.spring-context.xml
    • 3.spring-context-mybatis.xml
    • 4.spring-context-druid.xml
    • 5.mybatis-config.xml
    • 6.spring-mvc.xml
    • 7.web.xml
    • 8.log4j.properties（可选）
• 四、添加mvc的各种实现类(ssm搭建完结)
• 五、applicationContext.xml文件（可选）
• 其他：这里是 spring test 的类文件展示

一、使用IDEA创建maven项目

1.首先选择 File => New Project ,选择创建maven项目，勾选webapp骨架（使用骨架创建项目帮我们事先构建好web结构）

2.接下来按照图片选择并创建maven项目

3.创建成功后的项目结构展示

其中的src下的 main/java main/resource test/java test/resource 需要自行创建

二、向pom文件中导入相关jar包坐标

三、添加ssm和druid所需配置文件

pom坐标导入后，开始创建ssm配置文件
注意：所有配置文件均存放在 src/main/resources中
tips：如果你想使用spring的test，建议查看最后一节

1.db.properties

db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
db.username=root
db.password=root

db.initialSize=10
db.maxActive=50
db.minIdle=6
db.maxWait=60000
db.timeBetweenEvictionRunsMillis=60000
db.minEvictableIdleTimeMillis=300000
db.validationQuery=SELECT 'x'

db.filters=wall,stat

8.log4j.properties（可选）

日志文件，想添加就添加上(pom坐标已导入)

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=info, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=e:axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

四、添加mvc的各种实现类(ssm搭建完结)

此时ssm项目配置文件搭建完成，结构如下图所示，此时即可运行项目验证

五、applicationContext.xml文件（可选）

将刚才的 spring-context.xml spring-context-mybatis.xml spring-context-druid.xml 文件内容整合到applicationContext.xml文件中,减少配置文件数量
注意：合并后需要将web.xml中的spring路径修改成 classpath:applicationContext.xml

其他：这里是 spring test 的类文件展示

@RunWith(SpringJUnit4ClassRunner.class)
//这里要加载spring配置文件，classpath后不要忘了加 ` * `
@ContextConfiguration(locations = "classpath*:applicationContext.xml")
//@ContextConfiguration(locations = "classpath*:spring-context*.xml")
public class springTest {
    @Autowired
    private ProductMapper productMapper;
    @Autowired
    private ProductService productService;

    private ProductController productController = new ProductController();

    @Test
    public void run1() {
        productService.getList();
    }
}
