苍穹外卖第一天 搭建前端后端环境 先将代码提交到本地 然后在git上创建仓库 https://gitee.com/lh03062021/sky-take-out.git 点击push 定义远程仓库 把复制好的粘贴上去 就可以推送成功了。 导入sql文件,编译父项目
- nginx反向代理,将前端发送的动态请求由nginx转发到后端服务器
好处:负载均衡,提高访问速度,保证后端服务安全
2.完善登录功能,修改明文密码,改成md5加密(不能解密)
3.使用swagger
2.配置类加入配置
3.设置静态资源映射,否则接口文档页面无法访问
package com.sky.config;
import com.sky.interceptor.JwtTokenAdminInterceptor; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport; import springfox.documentation.builders.ApiInfoBuilder; import springfox.documentation.builders.PathSelectors; import springfox.documentation.builders.RequestHandlerSelectors; import springfox.documentation.service.ApiInfo; import springfox.documentation.spi.DocumentationType; import springfox.documentation.spring.web.plugins.Docket;
/**
-
配置类,注册web层相关组件 */ @Configuration @Slf4j public class WebMvcConfiguration extends WebMvcConfigurationSupport {
@Autowired private JwtTokenAdminInterceptor jwtTokenAdminInterceptor; /**
- 通过knife4j生成接口文档
- @return */ @Bean public Docket docket() { ApiInfo apiInfo = new ApiInfoBuilder() .title("苍穹外卖项目接口文档") .version("2.0") .description("苍穹外卖项目接口文档") .build(); Docket docket = new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo) .select() .apis(RequestHandlerSelectors.basePackage("com.sky.controller")) .paths(PathSelectors.any()) .build(); return docket; }
/**
- 设置静态资源映射
- @param registry */ @Override protected void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("/doc.html").addResourceLocations("classpath:/META-INF/resources/"); registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/"); } }
## - 32集 自定义注解开发,在工作中经常用到insertid,inserttime,updateid,updatetime
- 创建枚举型数据 insert或update
/**
* 数据库操作类型
*/
public enum OperationType {
/**
* 更新操作
*/
UPDATE,
/**
* 插入操作
*/
INSERT
}
@Target:用于描述注解的使用范围 @Rention:表示需要在什么什么级别保存该注释信息,用于描述注解的生命周期。(source<class<runtime) 2.创建注解接口类
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface AutoFill {
//只有数据库更新和插入操作
OperationType value();
}
3.创建aspect
package com.sky.aspect;
import com.sky.anocation.AutoFill;
import com.sky.constant.AutoFillConstant;
import com.sky.context.BaseContext;
import com.sky.entity.Employee;
import com.sky.enumeration.OperationType;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;
import java.lang.annotation.Annotation;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.text.SimpleDateFormat;
import java.util.Date;
/**

*/
@Aspect
@Component
@Slf4j
public class AutoFillAspect {
//定义切点
@Pointcut("execution(* com.sky.mapper.*.*(..)) && @annotation(com.sky.anocation.AutoFill)")
public void PointCut() {
}
@Before("PointCut()")
public void autoFill(JoinPoint joinPoint) {
log.info("开始进行公共字段填充...");
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
AutoFill autoFill = signature.getMethod().getAnnotation(AutoFill.class);
OperationType operationType = autoFill.value(); //获得数据库操作类型
Object[] args = joinPoint.getArgs();
if (args == null || args.length==0) {
return ;
}
Object entity = args[0];
Long currentId= BaseContext.getCurrentId();
SimpleDateFormat simpleDateFormat= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date a =new Date();
String s = simpleDateFormat.format(a);
if(operationType == OperationType.INSERT){
try {
Method setCreateTime = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_CREATE_TIME, String.class);
Method insertId = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_CREATE_USER, Long.class);
Method updateTime = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_UPDATE_TIME, String.class);
Method updateId = entity.getClass().getDeclaredMethod(AutoFillConstant.SET_UPDATE_USER, Long.class);
setCreateTime.invoke(entity,s);
insertId.invoke(entity,currentId);
updateTime.invoke(entity,s);
updateId.invoke(entity,currentId);
} catch (Exception e) {
e.printStackTrace();
}
}else if(operationType == OperationType.UPDATE){
try {

} catch (Exception e) {

}
