快速入门

本文提供了最基本的hsweb使用方式,只要认真阅读本文,创建一个项目不成问题.

目录

  1. 前言
  2. 创建项目
  3. 增删改查
  4. 更多教程

前言

hsweb是基于java8,spring-boot,mybatis开发.所以在开始使用hsweb的前,你至少应该掌握以下技术:java,maven. 最好掌握以下技术:spring-boot,mybatis. 如果对以上技术一无所知,请先去各大搜索引擎学习之.

hsweb是一个模块化的项目,对各个功能进行了细分,这是为了更好的拓展性,但是在实际业务项目中,并不需要这样的细分,因此,强烈不建议自己直接将hsweb-framework clone下来在上面添加业务代码,正确的姿势是使用maven,根据自己的需求依赖hsweb的各个模块.

hsweb 目前未提供前端支持,仅有一个demo可供参考.

本入门教程以一个最传统的单模块项目为例子. IDE为:Intellij IDEA(需安装lombok插件)

创建项目

  1. 新建maven项目:

新建项目

编辑pom.xml,然后reimport.如果对maven不够熟悉,maven的设置请使用默认设置,不要在settings.xml里自己添加私服. 否则可能出现依赖无法下载的问题.

  1. 在resources中创建application.yml配置 application.yml
server:
  port: 8080

spring:
  aop:
      auto: true
  datasource:
     type: com.alibaba.druid.pool.DruidDataSource
     driver-class-name : com.mysql.jdbc.Driver
     url : jdbc:mysql://localhost:3306/myproject?useSSL=false&useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false
     username : root
     password : root

hsweb:
  app:
    name: my-project
    version: 1.0.0

logging:
  level:
     org.hswebframework.web: DEBUG
     org.hswebframework.web.cache: WARN
     org.apache.ibatis: DEBUG
     org.mybatis: DEBUG
  1. 创建启动类 MyProjectApplication.java
package com.mycompany;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author zhouhao
 * @since 1.0
 */
@SpringBootApplication
public class MyProjectApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyProjectApplication.class,args);
    }
}
  1. 创建数据库
    CREATE DATABASE IF NOT EXISTS myproject default charset utf8 COLLATE utf8_general_ci;
  1. 执行MyProjectApplication.main启动应用 MyProjectApplication.java

打开浏览器访问 http://localhost:8080. 提示Whitelabel Error Page则说明服务启动成功. 因为现在还没有任何功能,所有提示错误信息.

到此,项目建立完成,和普通的spring-boot项目没有区别.

增删改查

使用通用CURD,添加一个增删改查功能:

在pom.xml中引入模块:

<!--通用CRUD-->
<dependency>
    <groupId>org.hswebframework.web</groupId>
    <artifactId>hsweb-commons-dao-mybatis</artifactId>
    <version>${hsweb.framework.version}</version>
</dependency>
<dependency>
    <groupId>org.hswebframework.web</groupId>
    <artifactId>hsweb-commons-service-simple</artifactId>
    <version>${hsweb.framework.version}</version>
</dependency>
<dependency>
    <groupId>org.hswebframework.web</groupId>
    <artifactId>hsweb-commons-controller</artifactId>
    <version>${hsweb.framework.version}</version>
</dependency>

引入curd依赖

  1. 创建数据库表:
    create table tb_test(
        id varchar(32) primary key,
        name varchar(32) not null,
        status tinyint,
        comment text
    )
  1. 创建实体类 com.mycompany.entity.TestEntity

实体类可通过继承:org.hswebframework.web.commons.entity.SimpleGenericEntity<主键类型>.来使用通用的crud功能.

@Getter
@Setter
public class TestEntity extends SimpleGenericEntity<String> {
    private String name;

    private Byte status;

    private String comment;
}

创建实体

  1. 创建Dao

dao接口可通过继承:org.hswebframework.web.dao.CrudDao<实体类,主键类型>.来使用通用的crud功能.

创建Dao接口 com.mycompany.dao.TestDao

public interface TestDao extends CrudDao<TestEntity,String> {

}

创建Dao

创建myabtis mapper,在resources目录上创建:com/mycompany/dao/mybatis/TestMapper.xml,注意: 目录分割使用/而不是.

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://www.mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.mycompany.dao.TestDao">
    <resultMap id="TestEntityResultMap" type="com.mycompany.entity.TestEntity">
        <!--必须列出映射关系-->
        <id property="id" column="id" javaType="String" jdbcType="VARCHAR"/>
        <result property="name" column="name" javaType="String" jdbcType="VARCHAR"/>
        <result property="status" column="status" javaType="Byte" jdbcType="TINYINT"/>
        <result property="comment" column="comment" javaType="String" jdbcType="CLOB"/>
    </resultMap>

    <!--用于动态生成sql所需的配置-->
    <sql id="config">
        <bind name="resultMapId" value="'TestEntityResultMap'"/>
        <bind name="tableName" value="'tb_test'"/>
    </sql>

    <insert id="insert" parameterType="com.mycompany.entity.TestEntity" >
        <include refid="config"/>
        <include refid="BasicMapper.buildInsertSql"/>
    </insert>

    <delete id="deleteByPk" parameterType="String">
        delete from tb_test where id =#{id}
    </delete>

    <delete id="delete" parameterType="org.hswebframework.web.commons.entity.Entity">
        <include refid="config"/>
        <include refid="BasicMapper.buildDeleteSql"/>
    </delete>

    <update id="update" parameterType="org.hswebframework.web.commons.entity.Entity">
        <include refid="config"/>
        <include refid="BasicMapper.buildUpdateSql"/>
    </update>

    <select id="query" parameterType="org.hswebframework.web.commons.entity.Entity" resultMap="TestEntityResultMap">
        <include refid="config"/>
        <include refid="BasicMapper.buildSelectSql"/>
    </select>

    <select id="count" parameterType="org.hswebframework.web.commons.entity.Entity" resultType="int">
        <include refid="config"/>
        <include refid="BasicMapper.buildTotalSql"/>
    </select>
</mapper>

创建Mybatis

在application.yml中添加配置:

mybatis:
  mapper-locations: classpath:com/mycompany/dao/mybatis/**/*.xml

在MyProjectApplication上添加注解:@MapperScan(basePackages = "com.mycompany.dao", markerInterface = org.hswebframework.web.dao.Dao.class)

  1. 创建Service

service接口可通过继承:org.hswebframework.web.service.CrudService<实体类,主键类型>.来使用通用的crud功能.

创建接口类: com.mycompany.service.TestService

public interface TestService extends CrudService<TestEntity,String> {
}

实现类可通过继承: org.hswebframework.web.service.GenericEntityService<实体类,主键类型>.来使用通用crud功能.

创建实现类 com.mycompany.service.impl.TestServiceImpl

@Service
public class TestServiceImpl extends GenericEntityService<TestEntity,String>
        implements TestService {

    @Autowired
    private TestDao testDao;

    @Override
    protected IDGenerator<String> getIDGenerator() {
        return IDGenerator.MD5;
    }

    @Override
    public TestDao getDao() {
        return testDao;
    }
}

创建Service

  1. 创建Controller

controller 可通过实现接口: org.hswebframework.web.controller.SimpleGenericEntityController<实体类,主键类型,org.hswebframework.web.commons.entity.param.QueryParamEntity>

创建controller类: com.mycompany.controller.TestController

@RestController
@RequestMapping("/test")
public class TestController implements SimpleGenericEntityController<TestEntity, String, QueryParamEntity> {

    @Autowired
    TestService testService;

    @Override
    public CrudService<TestEntity, String> getService() {
        return testService;
    }
}
  1. 测试

方式一:编写单元测试

在src/test/groovy目录下创建com.mycompany.TestApplication.java和com.mycompany.controller.TestControllerTest.groovy

@SpringBootApplication
@WebAppConfiguration
public class TestApplication {

}
@WebAppConfiguration
@ContextConfiguration
@SpringBootTest(classes = [TestApplication.class], properties = ["classpath:application.yml"])
class TestControllerTest extends Specification {
    @Autowired
    private ConfigurableApplicationContext context;

    @Shared
    private MockMvc mockMvc;

    void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
    }

    def "Test Create Data"() {
        setup:
        def testData = """
            {"name":"测试数据","status":1,"comment":"说明"}
            """
        and:
        mockMvc.perform(
                post("/test")
                        .contentType(MediaType.APPLICATION_JSON)
                        .content(testData)
        ).andExpect(status().is(201))

    }
}

执行单元测试,通过则说明新增功能测试通过.

方式二: postman 或者idea的Test Restful Web Servcice,以Idea工具为例:

执行启动类:com.mycompany.MyProjectApplication启动服务,然后调用/test服务

测试

一个最简单的通用crud例子完成了!!
