Question

我正在尝试使用Spring配置服务器。我想同时使用Spring安全性和JDBI。所以我配置了服务器的数据源（？）并将其链接到JDBI。但我无法在WebSecurityConfig中使用此数据源。

这是我的主配置java文件：

    @SpringBootApplication
    @EnableAutoConfiguration
    public class Application extends WebMvcConfigurerAdapter {

       private static DBI dbi = null;

       public static void main(String[] args) {
           SpringApplication.run(Application.class, args);
       }


       static DBI getDbi() {
           if(dbi == null) {
               DataSource ds = JdbcConnectionPool.create("jdbc:h2:mem:test", "ndl", "ndl");
               dbi = new DBI(ds);
           }
           return dbi;
       }
    }

这是安全弹簧的文件

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private DataSource dataSource;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/", "/home").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/login.html")
                .permitAll()
                .and()
                .logout()
                .permitAll();
        http.csrf().disable();
    }

    @Autowired
    public void configAuthentication(AuthenticationManagerBuilder auth) throws Exception {
        auth.jdbcAuthentication().dataSource(dataSource)
                .usersByUsernameQuery(
                        "select username,password from users where username=?")
                .authoritiesByUsernameQuery(
                        "select username, role from users where username=?");
    }

}

我收到了这个错误。

Field dataSource in rest.WebSecurityConfig required a bean of type 'javax.sql.DataSource' that could not be found.

我尝试在类中编写DataSource ds（而不是在方法中）。并添加注释@Bean。但我得到了另一个错误

   public static DataSource ds = JdbcConnectionPool.create("jdbc:h2:mem:test", "ndl", "ndl");

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public static DataSource getDataSource(){
        return ds;
    }

错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webSecurityConfig': Injection of autowired dependencies failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/jdbc/core/support/JdbcDaoSupport

我希望你有任何想法...... 谢谢;）

发现问题。

我错过了以下依赖项：spring-jdbc

所以我的最终build.gradle是

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.8.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'gs-rest-service'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
    maven {
        url 'https://repo.spring.io/libs-milestone'
    }
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile("org.springframework.boot:spring-boot-starter-security")
    testCompile("org.springframework.security:spring-security-test")
    compile group: 'org.jdbi', name: 'jdbi', version: '2.4.2'
    compile group: 'com.h2database', name: 'h2', version: '1.3.148'
    compile group: 'org.springframework', name: 'spring-jdbc', version: '4.3.8.RELEASE'
}
