SpringSecurity的官方文档及其简单，他的示例配置就是在xml文件中把用户名和密码写固定了，然而在实际工作中是不可能的，参考了下网上的教程发现良莠不齐，特此写下记录学习过程
首先pom导入jar包：
pom.xml

SpringSecurity.xml配置

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:security="http://www.springframework.org/schema/security"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
          http://www.springframework.org/schema/security
          http://www.springframework.org/schema/security/spring-security-4.1.xsd">
    <security:http auto-config="true">
        <security:intercept-url pattern="/index.jsp" access="hasRole('ROLE_ADMIN')" /><!-- access后面直接写"ROLE_ADMIN"这里会提示出错，提示找不到这种ROLE_ADMIN这种类型 -->
    </security:http>
    <!-- 查询网上的文章，这里都是引用的实现了UserDetailsService的类，但是我引用的时候提示UserDetailService不能转为org.springframework.security.authentication.AuthenticationProvider，所以这里需要改为实现了AuthenticationProvider的类 -->
    <bean id="MyUserService" class="szh.security.security.SecurityProvider"></bean>
    <security:authentication-manager>
        <security:authentication-provider
            ref="MyUserService">
        </security:authentication-provider>
    </security:authentication-manager>
</beans>

UserDetailService实现类

public class MyUserDetailService implements UserDetailsService  {

    @Override
    public UserDetails loadUserByUsername(String username)
            throws UsernameNotFoundException {
//在这里为了方便测试直接固定了
        MyUser myUser = new MyUser();
        System.out.println(username + "load的值");
        myUser.setUser_name("a");
        myUser.setUser_password("aa");
        myUser.setUser_role("ROLE_ADMIN");
        return new MyUserDetail(myUser, getAuthorities());
    }

    private Collection<GrantedAuthority> getAuthorities() {
        Collection<GrantedAuthority> grantedAuthorities = new ArrayList<>();
        SimpleGrantedAuthority grantedAuthority = new SimpleGrantedAuthority("ROLE_ADMIN");
        grantedAuthorities.add(grantedAuthority);
        return grantedAuthorities;
    }

}

MyUserDetail实现类：为了以后能更多的对用户进行操作

public class MyUserDetail implements UserDetails {
    private MyUser myUser;
    private Collection<? extends GrantedAuthority> authorities;

    public MyUserDetail(MyUser user,Collection<? extends GrantedAuthority> authorities) {
        this.myUser = user;
        this.authorities = authorities;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        // TODO Auto-generated method stub
        return authorities;
    }

    @Override
    public String getPassword() {
        return myUser.getUser_password();
    }

    @Override
    public String getUsername() {
        return myUser.getUser_name();
    }

    @Override
    public boolean isAccountNonExpired() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isAccountNonLocked() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isEnabled() {
        // TODO Auto-generated method stub
        return false;
    }

AuthenticationProvider类

public class SecurityProvider implements AuthenticationProvider {
    @Autowired
    private MyUserDetailService userDetailsService;
    @Override
    public Authentication authenticate(Authentication authentication)
            throws AuthenticationException {
        UsernamePasswordAuthenticationToken token = (UsernamePasswordAuthenticationToken) authentication;
        UserDetails userDetails = userDetailsService.loadUserByUsername("a");
        if (userDetails == null) {
            throw new UsernameNotFoundException("账号不存在");
        }
        return new UsernamePasswordAuthenticationToken(userDetails, "aa",
                userDetails.getAuthorities());
    }

    @Override
    public boolean supports(Class<?> authentication) {
        // TODO Auto-generated method stub
        return UsernamePasswordAuthenticationToken.class.equals(authentication);
    }

其他的正常配置即可
