文章目录一、配置事务依赖使用注解二、Elasticsearch创建项目配置maven完善依赖es连接配置实体映射repositoryservicecontroller三、swagger依赖启动类路径匹配配置配置类controller注解四、redis代码实现依赖yml配置配置类封装redisTamplate五、rabbitMQ依赖yml配置配置类生产者代码消费者代码测试一下一、配置事务
依赖 !-- 事务管理依赖以下二选一即可--!-- 用来开启事务使用 但是mybatis-plus-boot-starter默认引入了sprint-tx --
!-- dependency--
!-- groupIdorg.springframework/groupId--
!-- artifactIdspring-tx/artifactId--
!-- /dependency--!-- springboot整合的事务开启依赖无论是mybatis或是mybatis-plus都适用 --
!-- dependency--
!-- groupIdorg.springframework.boot/groupId--
!-- artifactIdspring-boot-starter-aop/artifactId--
!-- /dependency--使用注解
在启动类上添加注解
EnableTransactionManagement //开启事务在需要开启事务的类或者方法上使用注解前者表示该类的所有方法都开启事务后者表示只对具体的方法开启事务
Transactional(rollbackFor Exception.class)如果括号里不带参数表示仅在遇到运行时异常时才回滚而写了rollbackFor Exception.class表示遇到非运行时异常也回滚。
二、Elasticsearch
官方文档 Elasticsearch教程
自己搭建了一个简单的demo仓库在这里可以直接运行不过需要自行安装Elasticsearch7.16.3并在application.yml改一下url。
创建项目
用spring initializr 快速搭建一个项目sdk选的1.8java版本是8。
spring boot版本选择2.7.x。
勾选这些依赖 配置maven
file settings build,execution,deployment build tools maven 完善依赖
pom.xml
?xml version1.0 encodingUTF-8?
project xmlnshttp://maven.apache.org/POM/4.0.0 xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexsi:schemaLocationhttp://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsdmodelVersion4.0.0/modelVersionparentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion2.7.2/versionrelativePath/ !-- lookup parent from repository --/parentgroupIdtracy/groupIdartifactIdclaimnet-client/artifactIdversion0.0.1-SNAPSHOT/versionnameclaimnet-client/namedescriptionclaimnet客户端/descriptionpropertiesjava.version8/java.version/propertiesdependenciesdependencygroupIdorg.springframework.data/groupIdartifactIdspring-data-elasticsearch/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-devtools/artifactIdscoperuntime/scopeoptionaltrue/optional/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-configuration-processor/artifactIdoptionaltrue/optional/dependencydependencygroupIdorg.projectlombok/groupIdartifactIdlombok/artifactIdoptionaltrue/optional/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-test/artifactIdscopetest/scope/dependency/dependenciesbuildpluginsplugingroupIdorg.springframework.boot/groupIdartifactIdspring-boot-maven-plugin/artifactIdconfigurationexcludesexcludegroupIdorg.projectlombok/groupIdartifactIdlombok/artifactId/exclude/excludes/configuration/plugin/plugins/build/project
es连接配置
application.yml
spring:elasticsearch:rest:uris: http://es服务器ip:9200实体映射
package tracy.claimnetclient.entity;import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;import java.io.Serializable;Data
Document(indexName text,createIndex false) //如果Elasticsearch库中原本不存在这个索引的数据这里可以写true
public class Text implements Serializable {Id //将下面这个属性标记为idField(name id,type FieldType.Text)String id;Field(name application_no,type FieldType.Text)String applicationNo;Field(name content,type FieldType.Text)String content;Field(name date,type FieldType.Text)String date;Field(name entity,type FieldType.Text)String entity;Field(name feature,type FieldType.Text)String feature;
}注意这些属性和Elasticsearch数据库中对应文档中的属性是一一对应的。
repository
ElasticsearchRepository中提供了很多线程的方法可以满足简单的增删改查需求
package tracy.claimnetclient.repository;import org.springframework.data.domain.PageRequest;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import tracy.claimnetclient.entity.Text;
import java.util.List;public interface TextRepository extends ElasticsearchRepositoryText,String {//这里的String表示id的类型//PageRequest用来实现分页查询ListText findTextsByIdOrApplicationNoOrContent(String id, String app, String keyword, PageRequest pageRequest);
}
service
接口
package tracy.claimnetclient.service;import tracy.claimnetclient.entity.Text;
import tracy.claimnetclient.util.PairResult;import java.util.List;public interface TextService {ListText text(String keyword,Integer curPage,Integer pageSize);
}实现
package tracy.claimnetclient.service;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.PageRequest;
import org.springframework.stereotype.Service;
import tracy.claimnetclient.entity.Text;
import tracy.claimnetclient.repository.TextRepository;
import tracy.claimnetclient.util.PairResult;import java.util.Arrays;
import java.util.List;Service
public class TextServiceImpl implements TextService{Autowiredprivate TextRepository textRepository;Overridepublic ListText text(String keyword, Integer curPage, Integer pageSize) {if(curPagenull)curPage1;if(pageSizenull)pageSize10;return textRepository.findTextsByIdOrApplicationNoOrContent(keyword,keyword,keyword, PageRequest.of(curPage-1,pageSize));}
}controller
package tracy.claimnetclient.controller;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import tracy.claimnetclient.entity.Claim;
import tracy.claimnetclient.entity.Text;
import tracy.claimnetclient.service.ClaimService;
import tracy.claimnetclient.service.TextService;import java.util.List;RestController
RequestMapping(/search)
public class SearchController {Autowiredprivate TextService textService;GetMapping(/text/{keyword})public ListText text(PathVariable(keyword)String keyword,Integer curPage,Integer pageSize) {return textService.text(keyword,curPage,pageSize);}
}【OK】
三、swagger
参考
依赖 !-- 引入swagger相关的jar --dependencygroupIdio.springfox/groupIdartifactIdspringfox-boot-starter/artifactIdversion3.0.0/version/dependency启动类
类上添加注解EnableOpenApi
路径匹配配置
application.yml
spring:mvc:pathmatch:matching-strategy: ant_path_matcher配置类
package tracy.claimnetclient.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.service.VendorExtension;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import java.util.ArrayList;Configuration
public class SwaggerConfiguration {Beanpublic Docket docket() {//这里要配置controller包return new Docket(DocumentationType.OAS_30).select().apis(RequestHandlerSelectors.basePackage(tracy.claimnetclient.controller)).paths(PathSelectors.any()).build().apiInfo(setApiInfo());}private ApiInfo setApiInfo() {//作者信息Contact contact new Contact(tracy,https://blog.csdn.net/Tracycoder?spm1011.2415.3001.5343,1409568085qq.com);//项目描述ApiInfo info new ApiInfo(Claimnet-client Restful Api, , v1.0,https://blog.csdn.net/Tracycoder?spm1011.2415.3001.5343, contact,Apache 2.0, , new ArrayListVendorExtension());return info;}
}controller注解
使用类、方法、参数注解
package tracy.claimnetclient.controller;import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import tracy.claimnetclient.entity.Claim;
import tracy.claimnetclient.entity.Text;
import tracy.claimnetclient.service.ClaimService;
import tracy.claimnetclient.service.TextService;import java.util.List;Api(tags 检索模块)
RestController
RequestMapping(/search)
public class SearchController {Autowiredprivate TextService textService;Autowiredprivate ClaimService claimService;ApiOperation(value 根据id、申请号、内容查询text索引文档, notes api/search/text, response List.class)GetMapping(/text/{keyword})public ListText text(ApiParam(value 关键词, required true) PathVariable(keyword)String keyword,ApiParam(value 当前页码) Integer curPage,ApiParam(value 页大小) Integer pageSize) {return textService.text(keyword,curPage,pageSize);}
}
最后启动项目访问http://127.0.0.1:8080/swagger-ui/index.html。
四、redis代码实现
依赖 dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-data-redis/artifactIdversion2.5.9/version/dependencyyml配置
spring:redis:host: ip地址database: 0port: 6379配置类
package com.yy.myconfig;import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;/*** 自定义一个redis template模板*/
Configuration
public class RedisConfig {BeanSuppressWarnings(all)public RedisTemplateString, Object redisTemplate(RedisConnectionFactory factory) {//为了使开发方便直接使用String, ObjectRedisTemplateString, Object template new RedisTemplate();template.setConnectionFactory(factory);//Json序列化配置Jackson2JsonRedisSerializer jackson2JsonRedisSerializer new Jackson2JsonRedisSerializer(Object.class);ObjectMapper objectMapper new ObjectMapper();objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(objectMapper);//string的序列化StringRedisSerializer stringRedisSerializer new StringRedisSerializer();//key采用string的序列化方式template.setKeySerializer(stringRedisSerializer);//hash的key也是用string的序列化方式template.setHashKeySerializer(stringRedisSerializer);//value序列化方式采用jacksontemplate.setValueSerializer(jackson2JsonRedisSerializer);//hash的value序列化方式采用jacksontemplate.setHashValueSerializer(jackson2JsonRedisSerializer);template.afterPropertiesSet();return template;}
}

测试一下
在测试类中运行以下方法 Testvoid testProducer() {producer.send();}成功
