Springboot项目小笔记

本文主要记录我使用idea搭建springboot项目时小功能配置

ueditor富文本编辑器

1. yml文件配置

   #  富文本编辑器
   ue:
     server-url: /ueditor/jsp/controller

2. 依赖导入

   <dependency>
   	<groupId>cn.jasonone.ueditor</groupId>
   	<artifactId>ueditor-spring-boot-starter</artifactId>
   	<version>1.1.4</version>
   </dependency>

3. 导入ueditor

   <script type="text/plain" id="editor" name="sonContent"></script>

SpringBoot的yml文件配置

server:
  port: 80

logging:
  level:
    cn.blue: trace
    #优先级从高至低依次为：OFF、FATAL、ERROR、WARN、INFO、DEBUG、TRACE

# layui模板里的时间格式配置
spring:
  jackson:
    date-format: yyyy-MM-dd HH:mm
    time-zone: "GMT+8"     
---

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/rbac?serverTimezone=GMT%2b8
    username: root
    password:

# 开发阶段关闭thymeleaf的模板缓存
  thymeleaf:
    cache: false 
    
mybatis:
  mapper-locations: classpath:cn/blue/mapper/sqlmap/*.xml
  configuration:
    map-underscore-to-camel-case: true

#  配置别名扫描的包
  type-aliases-package: com.hm.publicraise.bean

#  头像存储位置
head-img-path: classpath:/static/upload/heads

#  头像存储位置
raise-img-path: classpath:/static/upload/raises

#  富文本编辑器
ue:
  server-url: /ueditor/jsp/controller

Invalid bound statement(not found)，访问不到mapper.xml

解决方法

application配置文件中mybatis配置

mybatis:
  mapper-locations: classpath:/mapper/*.xml
  configuration:
    map-underscore-to-camel-case: true

代码正确，无法访问controller层方法

其他包都得放在启动类包下

拦截器

登录拦截器

1.LoginController主要代码

/**
  * 登录方法
  */
@PostMapping
public String login(UserInfo userInfo, HttpSession session) {
    try {
        UserInfo user = userInfoService.findOneUser(userInfo);
        if (user != null) {
            //存放引用常量的位置：ApplicationConst
            session.setAttribute(ApplicationConst.LOGIN_SESSION_STATUS, user);
            return "index";
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    //重定向回去会调用controller，但是请求转发只会访问目录下的资源文件
    return "redirect:/login";
}

2.LoginHandlerInterceptor 登录拦截器

@Component
public class LoginHandlerInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        HttpSession session = request.getSession();
        UserInfo user = (UserInfo) session.getAttribute(ApplicationConst.LOGIN_SESSION_STATUS);
        if (user != null) {
            //放行
            return true;
        } else {
            response.sendRedirect(request.getContextPath() + "/login");
            return false;
        }
    }
}

3.配置WebMvcConfigurer 拦截器，将登录拦截器添加进去

@Configuration
public class MyWebMvcConfigurer implements WebMvcConfigurer {
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index");
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LoginHandlerInterceptor())
                //拦截所有
                .addPathPatterns("/**")
                //排除资源文件和登录、注销请求
                .excludePathPatterns("/login", "/logout")
                .excludePathPatterns("/layui/**", "/**/*.js")
                .excludePathPatterns("/**/*.jpg", "/**/*.png");
    }
}
