java Spring安全性：无法从字符串“admin”确定值类型

1 周，6 日 Questions & Answers

我正在做一个Spring应用程序，我想为用户实现一个基于角色的授权，所以我遵循了this教程。我遇到的问题是，我在尝试登录后收到以下错误：

以下是我的应用程序属性的外观：

myapp.queries.roles-query=select u.username, r.name from user u inner join users_roles ur on(u.userid=ur.userid) inner join role r on(ur.roleid=r.roleid) where u.username=?

我的安全配置如下所示：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
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.web.util.matcher.AntPathRequestMatcher;

import javax.sql.DataSource;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private DataSource dataSource;

    @Value("${myapp.queries.users-query}")
    private String usersQuery;

    @Value("${myapp.queries.roles-query}")
    private String rolesQuery;

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.
                jdbcAuthentication()
                .usersByUsernameQuery(usersQuery)
                .authoritiesByUsernameQuery(rolesQuery)
                .dataSource(dataSource);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.
                authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/login").permitAll()
                .antMatchers("/registration").permitAll()
                .antMatchers("/admin/**").hasAuthority("ROLE_ADMIN").anyRequest()
                .authenticated().and().csrf().disable().formLogin()
                .loginPage("/login").failureUrl("/login?error=true")
                .defaultSuccessUrl("/admin/home")
                .usernameParameter("username")
                .passwordParameter("password")
                .and().logout()
                .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
                .logoutSuccessUrl("/").and().exceptionHandling()
                .accessDeniedPage("/access-denied");
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web
                .ignoring()
                .antMatchers("/resources/**", "/static/**", "/css/**", "/js/**", "/images/**");
    }

}

这就是我的用户类的外观：

import javax.persistence.*;
import java.util.Collection;
import java.util.HashSet;
import java.util.Set;

@Entity
@Table(name="user")
public class User {

    @ManyToMany
    @JoinTable(
            name = "users_roles",
            joinColumns = @JoinColumn(
                    name = "userid", referencedColumnName = "id"),
            inverseJoinColumns = @JoinColumn(
                    name = "roleid", referencedColumnName = "id"))
    private Collection<Role> roles;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @Column(name = "username", nullable = false)
    private String username;


    @Column(name = "password", nullable = false)
    private String password;

    @ManyToMany(fetch = FetchType.LAZY,
            cascade = {
                    CascadeType.PERSIST,
                    CascadeType.MERGE
            },
            mappedBy = "users")
    private Set<Book> books = new HashSet<>();

    public Set<Book> getBooks() {
        return books;
    }

    public void setBooks(Set<Book> books) {
        this.books = books;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    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 Collection<Role> getRoles() {
        return roles;
    }

    public void setRoles(Collection<Role> roles) {
        this.roles = roles;
    }
}

这是我的pom。xml

我使用xampp提供的MySQL进行数据存储和hibernate，其中的用户表的id字段为int（11），用户名和密码字段为varchar（100）（顺便说一下，我还没有加密密码，它只是一个简单的varchar）。该表有一个字段1，admin，admin和一个字段2，usr，usr

我完全不知道问题出在哪里。我尝试在应用程序中使用“spring”而不是“myapp”。属性，但它不起作用

    users-query不能是任意格式，除非您还替换了从该查询中读取结果的组件

    在您的情况下，我相信Spring Security认为admin是您的密码，因为它是查询返回的第二列

        public static final String DEF_USERS_BY_USERNAME_QUERY = 
        "select username,password,enabled from users where username = ?";

    Spring Security当它queries the database does this

        protected List<UserDetails> loadUsersByUsername(String username) {
        return getJdbcTemplate().query(this.usersByUsernameQuery,
                new String[] { username }, new RowMapper<UserDetails>() {
                    @Override
                    public UserDetails mapRow(ResultSet rs, int rowNum)
                            throws SQLException {
                        String username = rs.getString(1);
                        String password = rs.getString(2);
                        boolean enabled = rs.getBoolean(3);
                        return new User(username, password, enabled, true, true, true,
                                AuthorityUtils.NO_AUTHORITIES);
                    }

                });
    }

    因此，问题的解决方案是让查询返回正确的信息
