Spring security + ldap

spring security 的java config方式配置

因为是在原有项目上配置spring security，之前spring配置使用的是xml方式，对于security的配置看网上大多数是使用java config的方式配置，所以想尝试采用java配置的方式

添加依赖

      <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-core</artifactId>
            <version>${springframework.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            <version>${springframework.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-ldap</artifactId>
            <version>${springframework.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            <version>${springframework.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-crypto</artifactId>
            <version>${springframework.version}</version>
        </dependency>

spring security config

创建一个servlet filter，注册到springSecurityFilterChain

@Configuration
@EnableWebSecurity
public class SecurityConfig  extends WebSecurityConfigurerAdapter{
    @Autowired
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .ldapAuthentication()
                .userSearchBase("ou=users")
                .userSearchFilter("(uid={0})")
                .groupSearchBase("ou=groups")
                .groupSearchFilter("memberUid={0}")
                .contextSource()
                .url("ldap://xxxxxxx")
                .root("dc=xxxxxxx")
                .managerDn("xxxxxxxxx")
                .managerPassword("xxxxxxx");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .formLogin()
                .loginPage("/login.jsp")
                .and()
                .authorizeRequests()
                .antMatchers("/baselines/info").authenticated()
                .antMatchers(HttpMethod.GET, "/baselines").hasRole("app-SW-functional")
                .anyRequest().denyAll();
    }
}

将filter注册到到应用

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
}

最简单的配置按说就已经完成了，但是启动spring却启动不起来,提示filter启动失败

找了很长时间的原因，跟书上的教程和网上的教程对比，都没发现问题在哪，最后从官方文档中看到如下信息，
