22 springboot中集成springsecurity并使用标签

项目中使用权限管理，springboot首选就是springsecurity。
pom.xml

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

然后就是application配置文件，用的是mysql数据库

# jdbc_config
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/iptrace?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false
spring.datasource.username=root
spring.datasource.password=root

表和数据，别问我为什么要这样建，springsecurity就是这样定义的，你写完它会自动提示少这两个表。密码和username一样

-- ----------------------------
-- Table structure for users
-- ----------------------------
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
  `username` varchar(50) NOT NULL,
  `password` varchar(100) NOT NULL,
  `enabled` tinyint(1) NOT NULL,
  PRIMARY KEY (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of users   
-- ----------------------------
INSERT INTO `users` VALUES ('admin', '$2a$10$CeIYm40M71/THnbCQ0fvGOzjJu7d9GTVKnkXyqXq/bkjQvfW6MoQ6', '1');
INSERT INTO `users` VALUES ('user', '$2a$10$eEhBAy0wNwiM.WGaqbtXEOrlC6TJcUXHuYKX8RcjxZRNaiCt5kFCy', '1');

-- ----------------------------
-- Table structure for authorities
-- ----------------------------
DROP TABLE IF EXISTS `authorities`;
CREATE TABLE `authorities` (
  `username` varchar(50) NOT NULL,
  `authority` varchar(50) NOT NULL,
  UNIQUE KEY `ix_auth_username` (`username`,`authority`),
  CONSTRAINT `fk_authorities_users` FOREIGN KEY (`username`) REFERENCES `users` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of authorities
-- ----------------------------
INSERT INTO `authorities` VALUES ('admin', 'ROLE_ADMIN');
INSERT INTO `authorities` VALUES ('user', 'ROLE_USER');

然后设置security文件

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.provisioning.JdbcUserDetailsManager;
import org.springframework.security.provisioning.UserDetailsManager;

import javax.sql.DataSource;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)//开启基于方法的声明式权限控制
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    protected DataSource datasource;

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/js/**", "/css/**", "/img/**", "/**/favicon.ico","/model/**","/picture/**","/plugin/**");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
            .authorizeRequests()
//               .antMatchers("/").hasRole("ROLE_USER")
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll().successForwardUrl("/phone")
                .and().rememberMe()
                .tokenValiditySeconds(2419200).and()

            .logout().logoutUrl("/logout")
                .permitAll();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    //内存中创建用户信息和角色
    //auth.inMemoryAuthentication().withUser("user").password("123").roles("USER");

    //默认数据库连接，方法在下面
    // auth.userDetailsService(jdbcUserDetailsManager());

       //自定义读取用户信息和角色
        auth.jdbcAuthentication().dataSource(datasource)
                .passwordEncoder(passwordEncoder())
                .usersByUsernameQuery("select username,password,1 as enabled from users where username=?")
                .authoritiesByUsernameQuery("select username,authority from authorities where username =?");
    }

    /* 采用jdbc方式 */
    public UserDetailsManager jdbcUserDetailsManager() throws Exception {
        JdbcUserDetailsManager userMan = new JdbcUserDetailsManager();
        userMan.setDataSource(datasource);
        return userMan;
    }

    //定义密码类型BCryptPasswordEncoder，当然也可以自定义密码类型（以后再说）
    @Bean
    public PasswordEncoder passwordEncoder(){
        PasswordEncoder encoder = new BCryptPasswordEncoder();
        return encoder;
    }
}

然后在前台就可以使用security标签操作权限了。

我用的是freemarker模板引擎。继续添加包。

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-taglibs</artifactId>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.2.1-b03</version>
    </dependency>

然后主要的是把spring-security-taglibs\4.2.4.RELEASE\spring-security-taglibs-4.2.4.RELEASE.jar!\META-INF\security.tld文件拷出来。放在resources/static/tags/下。

然后建个freemarker配置类

import freemarker.ext.jsp.TaglibFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;

import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.List;

@Configuration
public class TldConfig extends WebMvcConfigurerAdapter {

    @Autowired
    private FreeMarkerConfigurer configurer;

    @PostConstruct
    public void freeMarkerConfigurer() {
        List<String> tlds = new ArrayList<String>();
        tlds.add("/static/tags/security.tld");
        TaglibFactory taglibFactory = configurer.getTaglibFactory();
        taglibFactory.setClasspathTlds(tlds);
        if(taglibFactory.getObjectWrapper() == null) {
            taglibFactory.setObjectWrapper(configurer.getConfiguration().getObjectWrapper());
        }
    }
}

最后在页面头部引用
<#assign sec=JspTaglibs["http://www.springframework.org/security/tags"]/>

<@sec.authorize access="hasRole('ADMIN')">
     ***
</@sec.authorize>

这样的话，只有admin角色的可以查看，user进来看不见。
