                                <querydsl.packageSuffix>.dsl</querydsl.packageSuffix>
                            </options>

在插件中我們配置了 querydsl.packageSuffix 所以 生成的包路徑如下

此時重啓項目 會報錯 提示找不到 cn.zhangfusheng.user.model.QTbUser ,這是因爲我們配置了 dsl 的包前綴

解決辦法

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.querydsl.EntityPathResolver;
import org.springframework.data.querydsl.SimpleEntityPathResolver;

/**
 * query dsl 配置
 */
@Configuration
public class DataSourceQueryDslConfig {

    /**
     * 配置 query dsl 的前綴
     * @return
     */
    @Bean
    public EntityPathResolver entityPathResolver() {
        return new ProjectEntityPathResolver(".dsl");
    }

    public static class ProjectEntityPathResolver extends SimpleEntityPathResolver implements EntityPathResolver {

        /**
         * Creates a new {@link SimpleEntityPathResolver} with the given query package suffix.
         * @param querySuffix must not be {@literal null}.
         */
        public ProjectEntityPathResolver(String querySuffix) {
            super(querySuffix);
        }
    }
}
