14.SSM框架 SMBMS
MVC三层架构
1.搭建一个mawen-web项目
2.测试Tomcat正常运行
配置最新的web.xml配置 否则可能css风格无法呈现
3.导入相应的jar包
<dependencies> <dependency> <!-- 单元测试 可能会产生test标签 删除即可--> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <dependency> <!-- Jsp依赖--> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.3</version> <scope>provided</scope> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <!-- Servlet依赖--> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>4.0.1</version> <scope>provided</scope> </dependency> <!-- https://mvnrepository.com/artifact/taglibs/standard --> <dependency> <!-- Standard标签库--> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet.jsp.jstl/jstl-api --> <dependency> <!-- Jstl表达式依赖--> <groupId>javax.servlet.jsp.jstl</groupId> <artifactId>jstl-api</artifactId> <version>1.2</version> </dependency> <dependency> <!-- Java连接数据库--> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.47</version> </dependency> </dependencies>
4.编写实体类
Bill Provider Role User用户类 对应Smbms数据库的表单 表类映射
1.Bill
import java.math.BigDecimal;
import java.util.Date;
public class Bill {
private Integer id;
private String billCode;//账单编码

private String productUnit;//商品单位
private BigDecimal productCount;//商品数量
private BigDecimal totalPrice;//总金额
private Integer isPayment;//是否支付
private Integer providerId;//供应商ID
private Integer createdBy;//创建者
private Date creationDate;//创建时间
private Integer modifyDate;//更新时间
private String providerName;//供应商名称
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;

this.creationDate = creationDate;
}
public Integer getModifyDate() {
return modifyDate;
}
public void setModifyDate(Integer modifyDate) {

}
2.Provide

public void setId(Integer id) {
this.id = id;
}
public String getProCode() {
return proCode;
}
public void setProCode(String proCode) {

4.User
