package com.example.springboot_data.config; import com.alibaba.druid.pool.DruidDataSource; import com.alibaba.druid.support.http.StatViewServlet; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import javax.sql.DataSource; import java.util.HashMap; @Configuration public class DruidConfig { //绑定到yml中 @ConfigurationProperties(prefix = "spring.datasource") @Bean public DataSource druidDataSource(){ return new DruidDataSource(); } @Bean //后台监控功能 :spring可以在增加web功能下的web.xml中配置 但是springboot就通过ServletRegistrationBean配置 public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(new StatViewServlet(),"/druid/*"); //后台登录 账户密码配置 HashMap<String,String> initParameters = new HashMap<>(); //账户密码设置 initParameters.put("loginUsername","admin"); initParameters.put("loginPassword","admin"); // 禁止谁访问！ initParameters.put("ahui","192.168.11.12"); bean.setInitParameters(initParameters); System.out.println(bean.getInitParameters()+"this is getInit"); return bean; } } 8.3、实现filter过滤器 import org.springframework.context.annotation.Configuration; import javax.servlet.Filter; import javax.sql.DataSource; import java.util.HashMap; @Configuration public class DruidConfig { @Bean public FilterRegistrationBean webStatFilter(){ FilterRegistrationBean<Filter> bean = new FilterRegistrationBean<>(); bean.setFilter(new WebStatFilter()); // 过滤请求 HashMap<String, String> initParameters = new HashMap<>(); //过滤这些东西 initParameters.put("exclusions","*.js,*.css,/druid/*"); bean.setInitParameters(initParameters); return bean; } } 九、springboot整合mybatis 9.1、UserController实现跳转 package com.example.springboot_mybatis.controller; import com.example.springboot_mybatis.mapper.UserMapper; import com.example.springboot_mybatis.pojo.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RestController; import java.util.List; @RestController public class UserController { @Autowired(required = false) private UserMapper userMapper; @GetMapping("/queryUserList") public List<User> queryUserList(){ List<User> users = userMapper.queryUserList(); users.forEach(System.out::println); return users; } // 使用restful风格取值id 并查询 @GetMapping("/queryById/{id}") public User queryById( @PathVariable Integer id){ return userMapper.queryById(id); } } 9.2、UserMapper接口实现查询功能 package com.example.springboot_mybatis.mapper; import com.example.springboot_mybatis.pojo.User; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; import org.springframework.stereotype.Repository; import java.util.List; @Mapper // @Mapper表示这是一个mybatis的mapper类 // 也可以在主程序入口使用@MapperScan("com.example.springboot_mybatis.mapper")) @Repository //@Component public interface UserMapper { @Select("select * from user") List<User> queryUserList(); @Select("select * from user where id = #{id}") User queryById(@Param("id") int id); int addUser(@Param("User")User user); int updateUser(@Param("User")User user); int deleteUserById(@Param("id")int id); } 9.3、User实体类 package com.example.springboot_mybatis.pojo; import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor public class User { private Integer id; private String name; private Integer age; private String email; private Integer version; private String gmt_create; private String gmt_modified; } 9.4、yml配置连接数据库及绑定mybatis spring: datasource: type: org.springframework.jdbc.datasource.DriverManagerDataSource username: root password: root url: jdbc:mysql://localhost:3306/curry?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8 driver-class-name: com.mysql.cj.jdbc.Driver #整合mybatis mybatis: type-aliases-package: com.example.springboot_mybaits.pojo # mapper-locations: classpath:mybatis/mapper/*.xml 用注解就直接省去xml配置 十、SpringSecurity安全机制安全框架：shiro、springsecurity
安全框架的作用：认证、授权
功能权限
访问权限
菜单权限
重要security类：
webSecurityConfiguration : 自定义 security 策略
AuthenticationManagerBuilder ： 自定义认真策略
@EnableWebSecurity ： 开启 WebSecurity 模式
