MyBatis Pagehelper分页
1. pom引入pagehelper包
com.github.pagehelper
pagehelper-spring-boot-starter
1.2.3
2. 在application.properties配置PageHelper
#MyBatis分页插件配置
pagehelper.helperDialect=mysql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.params=count=countSql
3. 创建实体类
public class User {
Integer id;
String name;
Integer age;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
4. 创建mapper类userMapper
public interface UserMapper {
@Select("select * from user")
List findAll();
}
5.创建service类userService
@Service
public class UserService {
@Autowired
UserMapper userMapper;
public PageInfo findAll(int pageNum, int pageSize) {
PageHelper.startPage(pageNum, pageSize);
List userList = userMapper.findAll();
PageInfo pageInfo = new PageInfo<>(userList);
return pageInfo;
}
}
6. 创建 controller 类 UserController
@RestController
public class UserController {
@Autowired
UserService userService;
@GetMapping("findAll")
public PageInfo getUser(int pageNum, int pageSize) {
return userService.findAll(pageNum,pageSize);
}
}
7. 运行程序后，使用Http请求测试
Shiro-Spring-Boot-Web-Starter
1. pom文件导入jar包
org.apache.shiro
shiro-spring-boot-web-starter
1.4.0
com.github.theborakompanioni
thymeleaf-extras-shiro
2.0.0
2. 在application.properties配置Shiro
shiro.loginUrl=/login
shiro.successUrl=/home
shiro.unauthorizedUrl=/403
4. 创建编写shiroConfig配置类
package com.truth.bug.shiro;
import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.authz.AuthorizationException;
import org.apache.shiro.cache.CacheManager;
import org.apache.shiro.cache.MemoryConstrainedCacheManager;
import org.apache.shiro.realm.Realm;
import org.apache.shiro.spring.web.config.DefaultShiroFilterChainDefinition;
import org.apache.shiro.spring.web.config.ShiroFilterChainDefinition;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
@Configuration
@ControllerAdvice
public class ShiroConfig {
private Logger logger = LoggerFactory.getLogger(ShiroConfig.class);
/**
* 处理Shiro异常
*/
@ExceptionHandler(AuthorizationException.class)
@ResponseStatus(HttpStatus.FORBIDDEN)
public void authorizationExceptionHandler() {
logger.error("没有权限访问该资源");
}
@Bean
public Realm realm() {
return new MyShiroRealm();
}
@Bean
public CacheManager cacheManager() {
return new MemoryConstrainedCacheManager();
}
@Bean
public ShiroFilterChainDefinition shiroFilterChainDefinition() {
DefaultShiroFilterChainDefinition chainDefinition = new DefaultShiroFilterChainDefinition();
chainDefinition.addPathDefinition("/favicon.ico", "anon");
chainDefinition.addPathDefinition("/dist/**", "anon");
chainDefinition.addPathDefinition("/bootstrap/**", "anon");
chainDefinition.addPathDefinition("/plugins/**", "anon");
chainDefinition.addPathDefinition("/css/**", "anon");
chainDefinition.addPathDefinition("/js/**", "anon");
chainDefinition.addPathDefinition("/img/**", "anon");
chainDefinition.addPathDefinition("/", "anon");
chainDefinition.addPathDefinition("/logout", "logout");
chainDefinition.addPathDefinition("/**", "authc");
return chainDefinition;
}
@Bean
public ShiroDialect shiroDialect() {
return new ShiroDialect();
}
}
4. 编写自己Realm类
package com.truth.bug.shiro;
import com.truth.bug.entity.Role;
import com.truth.bug.entity.User;
import com.truth.bug.service.UserService;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
/**
* Created by Truth on 2018/8/31 0031 14:34
*/
public class MyShiroRealm extends AuthorizingRealm {
@Autowired
private UserService userService;
//用户认证
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
if (principalCollection == null){
throw new AuthenticationException("PrincipalCollection方法参数不能为null");
}
User user = (User) getAvailablePrincipal(principalCollection);
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
List roleList = user.getRoles();
Set roles = new HashSet<>();
for (int i = 0;i < roleList.size();i++){
roles.add(roleList.get(i).getRoleName());
}
info.setRoles(roles);
return null;
}
//用户认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
//加这一步的目的是在Post请求的时候会先进认证，然后在到请求
if (authenticationToken.getPrincipal() == null){
return null;
}
//获取用户信息
String phone = authenticationToken.getPrincipal().toString();
User user = userService.findUser(phone);
if (user == null){
//这里返回后会报出对应异常
return null;
}
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user,user.getPassword(),getName());
authenticationInfo.setCredentials(user);
return authenticationInfo;
}
}
4. Login控制器示例
@PostMapping("/login")
@ResponseBody
public AjaxResult login(String phone,String password, HttpSession session){
UsernamePasswordToken token = new UsernamePasswordToken(phone, DigestUtils.md5Hex(password + passwordSalt));
Subject subject = SecurityUtils.getSubject();
try {
subject.login(token);
session.setAttribute("user",subject.getPrincipal());
return AjaxResult.success();
}catch (AuthenticationException ex){
return AjaxResult.error("账号或密码错误");
}
}
5.登录用户修改个人信息后，不重新登陆进行同步更新
public AjaxResult updateUser(User user){
User user1 = (User)SecurityUtils.getSubject().getPrincipal();
userService.updateUser(user);
user1.setUserName(user.getUserName());
return AjaxResult.success();
}
