简单的shiro案例（springboot+mybatis）
1，导入maven

runtime

provided

provided

1.2
com.google.guava

2.配置druid文件
package com.example.demo.config;
import com.alibaba.druid.filter.Filter;
import com.alibaba.druid.filter.stat.StatFilter;
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.google.common.collect.Lists;
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;
/**druid的配置类
* @author sy
* @date 2019/3/14 17:35
*/
@Configuration
public class DruidConfig {
//会扫描application.properties文件的以spring.druid开头的数据注入
@ConfigurationProperties(prefix = "spring.druid")
@Bean(initMethod = "init",destroyMethod = "close") //跟着spring一块启动，一块关闭
public DruidDataSource dataSource(){
DruidDataSource dataSource = new DruidDataSource();
dataSource.setProxyFilters(Lists.newArrayList(statFilter()));//Lists是guava包
return dataSource;
}
//alibaba的监听器，打印慢sql
@Bean
public Filter statFilter(){
StatFilter filter = new StatFilter();
filter.setSlowSqlMillis(1);
filter.setLogSlowSql(true);
filter.setMergeSql(true);
return filter;
}
@Bean
public ServletRegistrationBean servletRegistrationBean(){
return new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
}
}
3，配置application.xml
#druid 阿里巴巴下的一个开源连接池：功能强大，可以监控，稳定。
spring.druid.driverClassName=com.mysql.cj.jdbc.Driver
spring.druid.url=jdbc:mysql://localhost:3306/shiro?characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&useSSL=false
spring.druid.username=root
spring.druid.password=root
#最大连接数
spring.druid.maxActive=30
#最小连接数
spring.druid.minIdle=5
#获取连接的最大等待时间
spring.druid.maxWait=10000
#解决mysql8小时的问题
spring.druid.validationQuery=SELECT 'x'
#Mybatis配置
mybatis.mapper-locations=mapper/*.xml
mybatis.type-aliases-package=com.example.demo.model
4，创建简单的对象：permission,role ,user
package com.example.demo.model;
import java.io.Serializable;
public class Permission implements Serializable {
private Integer pid;
private String name;
public Integer getPid() {
return pid;
}
public void setPid(Integer pid) {
this.pid = pid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
package com.example.demo.model;
import org.eclipse.jdt.internal.compiler.util.HashSetOfInt;
import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;
public class Role implements Serializable {
private Integer rid;
private String name;
private Set permissionSet = new HashSet();
public Integer getRid() {
return rid;
}
public void setRid(Integer rid) {
this.rid = rid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Set getPermissionSet() {
return permissionSet;
}
public void setPermissionSet(Set permissionSet) {
this.permissionSet = permissionSet;
}
}
package com.example.demo.model;
import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;
public class User implements Serializable {
private Integer uid;
private String username;
private String password;
private Set roleSet = new HashSet();
public Integer getUid() {
return uid;
}
public void setUid(Integer uid) {
this.uid = uid;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Set getRoleSet() {
return roleSet;
}
public void setRoleSet(Set roleSet) {
this.roleSet = roleSet;
}
}
5，创建controller，service，dao
//controller
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/getUserRole")
@ResponseBody
public User getUserRole(@RequestParam("username") String username){
return userService.getUserByUsername(username);
}
}
//service
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserMapper userMapper;
/**
* 通过username获取user
* @return
*/
@Override
public User getUserByUsername(String username) {
return userMapper.getUserByUsername(username);
}
}
//mapper
@Repository
public interface UserMapper {
User getUserByUsername(@Param("username") String username);
}
6，写xml文件，，，
7，建表，数据库表：shiro
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for permission
-- ----------------------------
DROP TABLE IF EXISTS `permission`;
CREATE TABLE `permission` (
`pid` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(20) CHARACTER SET utf8 NOT NULL,
PRIMARY KEY (`pid`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=latin1;
-- ----------------------------
-- Records of permission
-- ----------------------------
INSERT INTO `permission` VALUES ('1', 'update');
INSERT INTO `permission` VALUES ('2', 'delete');
INSERT INTO `permission` VALUES ('3', 'create');
INSERT INTO `permission` VALUES ('4', 'read');
-- ----------------------------
-- Table structure for role
-- ----------------------------
DROP TABLE IF EXISTS `role`;
CREATE TABLE `role` (
`rid` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(20) CHARACTER SET utf8 NOT NULL,
PRIMARY KEY (`rid`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
-- ----------------------------
-- Records of role
-- ----------------------------
INSERT INTO `role` VALUES ('1', 'admin');
INSERT INTO `role` VALUES ('2', 'user');
-- ----------------------------
-- Table structure for role_permission
-- ----------------------------
DROP TABLE IF EXISTS `role_permission`;
CREATE TABLE `role_permission` (
`pid` int(11) NOT NULL,
`rid` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
-- ----------------------------
-- Records of role_permission
-- ----------------------------
INSERT INTO `role_permission` VALUES ('1', '1');
INSERT INTO `role_permission` VALUES ('2', '1');
INSERT INTO `role_permission` VALUES ('3', '1');
INSERT INTO `role_permission` VALUES ('4', '1');
INSERT INTO `role_permission` VALUES ('4', '2');
-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`uid` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(20) CHARACTER SET utf8 NOT NULL,
`password` varchar(255) CHARACTER SET utf8 NOT NULL,
PRIMARY KEY (`uid`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('1', '张三', '123456');
INSERT INTO `user` VALUES ('2', '王五', '123546');
-- ----------------------------
-- Table structure for user_role
-- ----------------------------
DROP TABLE IF EXISTS `user_role`;
CREATE TABLE `user_role` (
`uid` int(11) NOT NULL,
`rid` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
-- ----------------------------
-- Records of user_role
-- ----------------------------
INSERT INTO `user_role` VALUES ('1', '1');
INSERT INTO `user_role` VALUES ('2', '2');8，在springboot启动类添加MapperScan扫描
//扫描Mapper文件，注入service的成员变量中。
@SpringBootApplication
@MapperScan(basePackages = "com.example.demo.mapper")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}9，启动tomcat，然后访问： http://localhost:8080/user/getUserRole?username=张三
