springboot只对指定类注入bean

@Bean
@ConditionalOnClass(
    name = {"org.springframework.security.core.session.SessionRegistry"}
)

@Configuration
@ConditionalOnProperty(
    prefix = "redis.session",
    value = {"enable-redis-session"},
    havingValue = "true"
)

@EnableConfigurationProperties({RedisSessionCustomConfig.class})

Resource[]=new org.springframework.core.io.support.ResourcePatternResolver.getResources("classpath*:" + path + "/**/*.class")

@Bean
@ConditionalOnMissingBean({IMuiltiDataSourcesConfig.class})
public IMuiltiDataSourcesConfig muiltiDataSourcesConfig() {
    MuiltiDataSourcesConfig mdsc = new MuiltiDataSourcesConfig();
    return mdsc;
}

@ConditionalOnMissingBean(
    name = {"gavinTransactionManager"}
)
public PlatformTransactionManager transactionManager(List<DataSource> dataSources) {
    List<DataSourceTransactionManager> tranManagers = new ArrayList();
    dataSources = (List)dataSources.stream().distinct().collect(Collectors.toList());
    Iterator var3 = dataSources.iterator();

    while(var3.hasNext()) {
        DataSource ds = (DataSource)var3.next();
        DataSourceTransactionManager tran = new DataSourceTransactionManager(ds);
        tranManagers.add(tran);
    }

    ChainedTransactionManager chainedTransactionManager = new ChainedTransactionManager((PlatformTransactionManager[])tranManagers.toArray(new PlatformTransactionManager[0]));
    return chainedTransactionManager;
}

@Bean
public StatFilter statFilter() {
    StatFilter statFilter = new StatFilter();
    statFilter.setMergeSql(true);
    statFilter.setSlowSqlMillis(5000L);
    statFilter.setLogSlowSql(true);
    return statFilter;
获取spring里边全局的bean

public class ConfigUtil implements ApplicationContextAware {
    public static ApplicationContext applicationContext;
    public static IdGenerator idgen;

    public ConfigUtil() {
    }

    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        applicationContext = applicationContext;
        idgen = (IdGenerator)applicationContext.getBean("idGenerator");
    }

    public static String nextId() throws Exception {
        if (idgen == null) {
            throw new Exception("IoC未初始化完成，请待初始化完成后调用。");
        } else {
            return String.valueOf(idgen.nextId());
        }
    }
}

@Bean
public Slf4jLogFilter logFilter() {
    Slf4jLogFilter logFilter = new Slf4jLogFilter();
    logFilter.setConnectionLogEnabled(false);
    logFilter.setStatementLogEnabled(true);
    logFilter.setResultSetLogEnabled(true);
    logFilter.setStatementExecutableSqlLogEnable(true);
    return logFilter;
}

@Bean
public ServletRegistrationBean druidServlet() {
    ServletRegistrationBean reg = new ServletRegistrationBean();
    reg.setServlet(new StatViewServlet());
    reg.addUrlMappings(new String[]{"/druid/*"});
    reg.setEnabled(this.mybatisCustomerConfig.getStateViewEnabled());
    reg.addInitParameter("loginUsername", this.mybatisCustomerConfig.getStatViewUserName());
    reg.addInitParameter("loginPassword", this.mybatisCustomerConfig.getStatViewPassword());
    reg.addInitParameter("logSlowSql", "true");
    return reg;
}

@Bean
public FilterRegistrationBean filterRegistrationBean() {
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
    filterRegistrationBean.setFilter(new WebStatFilter());
    filterRegistrationBean.addUrlPatterns(new String[]{"/*"});
    filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
    filterRegistrationBean.addInitParameter("profileEnable", "true");
    return filterRegistrationBean;
}
