1、使用IDEA建立maven项目

1.首先选择 File => New Project ,选择建立maven项目，勾选webapp骨架（使用骨架建立项目帮咱们事先构建好web结构）

2.接下来按照图片选择并建立maven项目

3.建立成功后的项目结构展现

其中的src下的 main/java main/resource test/java test/resource 须要自行建立css

2、向pom文件中导入相关jar包坐标

3、添加ssm和druid所需配置文件

pom坐标导入后，开始建立ssm配置文件
注意：全部配置文件均存放在 src/main/resources中
tips：若是你想使用spring的test，建议查看最后一节html

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.testWhileIdle=true
db.testOnBorrow=false
db.testOnReturn=false

db.poolPreparedStatements=false
db.maxPoolPreparedStatementPerConnectionSize=20
db.filters=wall,stat

4、添加mvc的各类实现类(ssm搭建完结)

此时ssm项目配置文件搭建完成，结构以下图所示，此时便可运行项目验证java

5、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,减小配置文件数量
注意：合并后须要将web.xml中的spring路径修改为 classpath:applicationContext.xmlmysql

其余：这里是 spring test 的类文件展现

@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();
    }
}
