1、使用IDEA建立maven項目

1.首先選擇 File => New Project ,選擇建立maven項目，勾選webapp骨架（使用骨架建立項目幫咱們事先構建好web結構）

2.接下來按照圖片選擇並建立maven項目

3.建立成功後的項目結構展現

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

2、向pom文件中導入相關jar包座標

3、添加ssm和druid所需配置文件

pom座標導入後，開始建立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，建議查看最後一節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的各類實現類(ssm搭建完結)

此時ssm項目配置文件搭建完成，結構以下圖所示，此時便可運行項目驗證java

5、applicationContext.xml文件（可選）

將剛纔的 spring-context.xml spring-context-mybatis.xml spring-context-druid.xml 文件內容整合到applicationContext.xml文件中,減小配置文件數量
注意：合併後須要將web.xml中的spring路徑修改爲 classpath:applicationContext.xmlmysql

其餘：這裏是 spring test 的類文件展現

@RunWith(SpringJUnit4ClassRunner.class)
//這裏要加載spring配置文件，classpath後不要忘了加 ` * `
@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();
    }
}
