使用Java Built Path将Spring项目添加到Spring Boot

我有一个连接到MongoDB的项目，配置如下：

@Configuration
@ComponentScan(basePackages = "ups.mongo")
@EnableMongoRepositories({ "ups.mongo.repository" })
public class SpringMongoConfig {

    @Bean
    public MongoDbFactory mongoDbFactory() throws Exception {
        return new SimpleMongoDbFactory(new MongoClient("127.0.0.1"), "ReconInput");
    }

    @Bean
    public MongoTemplate mongoTemplate() throws Exception {

        MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());

        return mongoTemplate;

    }
}

另一个项目是基于Spring启动的，配置了Spring安全性：

@Configuration
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private AccessDeniedHandler accessDeniedHandler;

    @Autowired
    private AuthenticateSuccessHandler successHandler;

    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public BCryptPasswordEncoder bCryptPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
            .authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/admin/**").hasAuthority("Admin")
                .antMatchers("/common/**").hasAnyAuthority("Admin","User")
                .antMatchers("/home").hasAnyAuthority("Admin","User")
                .and()
            .formLogin()
                .loginPage("/login")
                .successHandler(successHandler).permitAll()
                .and()
            .logout().permitAll()
                .and()
            .exceptionHandling()
                .accessDeniedHandler(accessDeniedHandler);
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder());
    }
}

If I run one by one without reference from Spring Boot App to Mongo Connection Project, it work properly. Contrary, It throw an error:

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名为'springSecurityConfig'的bean时出错：通过方法'setContentNegotationStrategy'参数0表示不满意的依赖关系;嵌套异常是org.springframework.beans.factory.BeanCreationException：在类路径资源中定义名称为'mvcContentNegotiationManager'的bean时出错[org / springframework / boot / autoconfigure / web / WebMvcAutoConfiguration $ EnableWebMvcConfiguration.class]：通过工厂方法进行Bean实例化失败;嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化[org.springframework.web.accept.ContentNegotiationManager]：工厂方法'mvcContentNegotiationManager'抛出异常;嵌套异常是java.lang.AbstractMethodError

有人可以建议或给我一些经验吗？

非常感谢！
