基于spring security实现接口权限控制

一、基于注解
（1）在security配置文件上配置@EnableGlobalMethodSecurity(prePostEnabled = true)注解
（2）在具体类上加@PreAuthorize("hasAuthority('admin_s1')")或者方法上加上@PreAuthorize("hasAuthority('admin_s1')")
代码示例如下

package com.ysh.springboot.test.config;

import com.sayo.authlogin.auth.JwtAuthenticationFilter;
import com.sayo.authlogin.service.DatabaseUserDetailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
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.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.web.AuthenticationEntryPoint;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;


@EnableWebSecurity

@EnableGlobalMethodSecurity(prePostEnabled = true)

public class WebSecurityConfig {

    @Configuration
    public static class MySecurityConfig extends WebSecurityConfigurerAdapter {

        @Autowired
        @Qualifier("databaseUserDetailService")
        private DatabaseUserDetailService userDetailsService;

        @Autowired
        @Qualifier("authenticationSuccessHandler")
        private AuthenticationSuccessHandler successHandler;

        @Autowired
        @Qualifier("authenticationFailHandler")
        private AuthenticationFailHandler failHandler;

        @Autowired
        @Qualifier("authenticationEntryPointImpl")
        private AuthenticationEntryPoint entryPoint;

        @Bean
        public JwtAuthenticationFilter getJwtAuthenticationFilter(){
            return new JwtAuthenticationFilter();
        }

        @Override
        public void configure(HttpSecurity http) throws Exception {
           // http.addFilterBefore(getJwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
            http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                    .and().csrf().disable()
                    .authorizeRequests()
                    .antMatchers("/v2/api-docs/**").permitAll()
                    .anyRequest().authenticated()
                    .and().formLogin().loginProcessingUrl("/api/login")
                    .successHandler(successHandler)
                    .failureHandler(failHandler)
                    .and().exceptionHandling().authenticationEntryPoint(entryPoint);
        }

        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(userDetailsService);
        }
    }
}

package com.ysh.springboot.test.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.security.core.Authentication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.ysh.springboot.test.service.UserService;
import com.ysh.springboot.test.valueobject.UserView;


@RestController
@RequestMapping("/api")

//@PreAuthorize("hasAuthority('admin_s1')")

public class UserController {

    @Autowired
    private UserService userService;

    @GetMapping(value = "/user")
    public UserView getUserByName(@RequestParam("userName") String userName,Authentication au) {
        System.out.println("11111111111");
        System.out.println(au);
        return userService.getUserByUserName(userName);
    }

@PreAuthorize("hasAuthority('admin_s1')")

    @GetMapping(value = "/user2")
    public UserView getUserByName2(@RequestParam("userName") String userName,Authentication au) {
        System.out.println("11111111111");
        System.out.println(au);
        return userService.getUserByUserName(userName);
    }
}

package com.ysh.springboot.test.service;

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.ysh.springboot.test.domain.User;
import com.ysh.springboot.test.repository.UserRepository;
import com.ysh.springboot.test.valueobject.UserView;

@Service
public class UserService {

    @Autowired
    private UserRepository userRepository;

@PreAuthorize("hasAuthority('admin_s11')")

    @Transactional
    public UserView getUserByUserName(String userName){

        UserView userView = new UserView();
        User user = userRepository.findByUserName(userName);
        userView.setUserName(user.getUserName());
        userView.setUserDesc(user.getUserDescription());
        List<String> roleCodes = new ArrayList<>();
        user.getRoles().stream().forEach(role -> roleCodes.add(role.getRoleCode()));
        userView.setRoleCodes(roleCodes);
        return userView;
    }
}

二、基于SecurityConfig配置类

   @Override
        public void configure(HttpSecurity http) throws Exception {
            http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                    .and().csrf().disable()
                    .authorizeRequests()
                    .antMatchers("/v2/api-docs/**").permitAll()

.antMatchers("/api/*").access("hasAuthority('admin_s3')")

                    .anyRequest().authenticated()
                    .and().formLogin().loginProcessingUrl("/api/login")
                    .successHandler(successHandler)
                    .failureHandler(failHandler)
                    .and().exceptionHandling().authenticationEntryPoint(entryPoint);
        }
