作者: dxyong | 来源:发表于2018-09-27 15:41 被阅读0次

    1.新建maven Web项目

    image image

    选择maven所在目录conf下的settings.xml文件,repository选择maven仓库的路径

    image image

    web项目创建成功

    image

    2.搭建SSM代码目录框架

    2.1创建项目代码目录

    src的main下新建resources,在resources目录下右键->Mark Directory as->resourcesRoot,然后在src下新建java目录,在java目录下右键->Mark Directory as->Sourcse Root,然后在java下新建包

    com.noah.contacts.bean -------->实体对象,对应数据库中的表

    com.noah.contacts.controller -------->web 接口路由控制

    com.noah.contacts.service -------->web 服务

    com.noah.contacts.dao -------->数据库访问

    com.noah.contacts.mapper -------->数据库到实体映射

    com.noah.contacts.swagger -------->swagger API框架

    2.3 修改web.xml
    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>
    
      <!-- 配置DispatcherServlet -->
      <servlet>
        <servlet-name>SpringMVC</servlet-name>

      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
    
    </web-app>
    
    2.4 在resources下新增spring-mvc.xml如下:
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           http://www.springframework.org/schema/context/spring-context.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    
        <!-- 扫描web相关的bean -->
        <context:component-scan base-package="com.noah.contacts.controller"/>
    
        <!-- 开启SpringMVC注解模式 -->
        <mvc:annotation-driven/>
    
        <!-- 静态资源默认servlet配置 -->
        <mvc:default-servlet-handler/>
    
        <!--重要!将你的SwaggerConfig配置类注入-->
        <bean class="com.noah.contacts.swagger.SwaggerConfig"/>
        <!--重要!配置swagger资源不被拦截-->
        <mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/" />
        <mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/" />
    
        <!-- 配置jsp 显示ViewResolver -->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
            <property name="prefix" value="/WEB-INF/views/"/>
            <property name="suffix" value=".jsp"/>
        </bean>
    
        <!-- 配置json转换器 -->
        <bean id="jsonMessageConverters" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="supportedMediaTypes">

                </list>
            </property>
        </bean>
    </beans>
    
    2.5 在swagger包下新建SwaggerConfig.java文件如下,配置Swagger
    package com.noah.contacts.swagger;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.test.context.web.WebAppConfiguration;
    import org.springframework.web.servlet.config.annotation.EnableWebMvc;
    import springfox.documentation.builders.ApiInfoBuilder;
    import springfox.documentation.builders.RequestHandlerSelectors;
    import springfox.documentation.service.ApiInfo;
    import springfox.documentation.spi.DocumentationType;
    import springfox.documentation.spring.web.plugins.Docket;
    import springfox.documentation.swagger2.annotations.EnableSwagger2;
    
    /*重要!如果你的项目引入junit测试,此处需要使用@WebAppConfiguration,如果没有使用junit使用@Configuration(很多的博客都没有注明这个问题,为此我花了非常多的时间解决问题)*/
    @WebAppConfiguration
    @EnableSwagger2//重要!
    @EnableWebMvc
    @ComponentScan(basePackages = "com.XXXXX.control")//扫描control所在的package请修改为你control所在package
    public class SwaggerConfig {
        @Bean
        public Docket api() {
            return new Docket(DocumentationType.SWAGGER_2)
                    .select()
                    .apis(RequestHandlerSelectors.any())
                    .build()
                    .apiInfo(apiInfo());
        }
        private ApiInfo apiInfo() {
            return new ApiInfoBuilder()
                    .title("XXX项目接口文档")
                    .description("XXX项目接口测试")
                    .version("1.0.0")
                    .termsOfServiceUrl("")
                    .license("")
                    .licenseUrl("")
                    .build();
        }
    }
    
    
    2.6 在resources下新增mybatis配置文件spring-mybatis.xml如下:
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           http://www.springframework.org/schema/tx/spring-tx.xsd">
    
        <!-- 扫描service包下所有使用注解的类型 -->

        <!-- 配置数据库相关参数properties的属性:${url} -->
        <context:property-placeholder location="classpath:jdbc.properties"/>
    
        <!-- 数据库连接池 -->
        <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
            <property name="driverClass" value="${jdbc.driver}"/>

            <property name="checkoutTimeout" value="${c3p0.checkoutTimeout}"/>
            <property name="acquireRetryAttempts" value="${c3p0.acquireRetryAttempts}"/>
        </bean>
    
        <!-- 配置SqlSessionFactory对象 -->
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <!-- 注入数据库连接池 -->
            <property name="dataSource" ref="dataSource"/>
            <!-- 扫描model包 使用别名 -->
            <property name="typeAliasesPackage" value="com.noah.model"/>
            <!-- 扫描sql配置文件:mapper需要的xml文件 -->
            <property name="mapperLocations" value="classpath:com/noah/contacts/mapper/*.xml"/>
        </bean>
    
        <bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">

        <!-- 配置基于注解的声明式事务 -->
        <tx:annotation-driven transaction-manager="transactionManager"/>
    
    </beans>
    
    2.7 在resources目录下新增数据库连接配置文件jdbc.properties如下:
    jdbc.driver=com.mysql.cj.jdbc.Driver
    #数据库地址
    jdbc.url=jdbc:mysql://localhost:3306/contacts?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Hongkong
    #用户名
    jdbc.username=xxxx
    #密码
    jdbc.password=xxxxxxxxx
    #最大连接数
    c3p0.maxPoolSize=30
    #最小连接数
    c3p0.minPoolSize=10
    #关闭连接后不自动commit
    c3p0.autoCommitOnClose=false
    #获取连接超时时间
    c3p0.checkoutTimeout=10000
    #当获取连接失败重试次数
    c3p0.acquireRetryAttempts=2
    
    2.8 在resources目录下添加mybatis自动映射配置(pom.xml中插件中声明的配置文件),MyBatis Generator自动生成实体、mapper和dao层
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE generatorConfiguration
            PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN "

        <context id="default" targetRuntime="MyBatis3">
    
            <!-- optional,旨在创建class时,对注释进行控制 -->
            <commentGenerator>
                <property name="suppressDate" value="true"/>
                <property name="suppressAllComments" value="true"/>
            </commentGenerator>
    
            <!--jdbc的数据库连接 -->

    运行方法:使用maven运行mybatis-generator-maven-plugin插件:工程名->Plugins->mybatis-generator->mybatis-generator:generate->Run Maven Build,这里自动生成了数据库中的User表。

    3.编写测试代码

    先把项目的结构晒一下


    image.png
    3.1 修改User.java ,之前用的mybatis-generator-maven-plugin插件虽然通过配置文件自动生成了 bean、dao、mapper,但是生成的代码看起来不太简洁,后面就改用tk.mybatis的框架(前面的pom.xml中已经集成)
    package com.noah.contacts.bean;
    
    import javax.persistence.Column;
    import javax.persistence.Id;
    import javax.persistence.Table;
    import java.util.Date;
    
    /***
     * 表名默认使用类名,驼峰转下划线(只对大写字母进行处理),如UserInfo默认对应的表名为user_info。
     * 表名可以使用@Table(name = "tableName")进行指定,对不符合第一条默认规则的可以通过这种方式指定表名.
     * 字段默认和@Column一样,都会作为表字段,表字段默认为Java对象的Field名字驼峰转下划线形式.
     * 可以使用@Column(name = "fieldName")指定不符合第3条规则的字段名
     * 使用@Transient注解可以忽略字段,添加该注解的字段不会作为表字段使用.
     * 建议一定是有一个@Id注解作为主键的字段,可以有多个@Id注解的字段作为联合主键.
     * 如果是MySQL的自增字段,加上@GeneratedValue(generator = "JDBC")即可。如果是其他数据库,可以参考官网文档。

    @Table(name="user")
    public class User {
        @Id
        @Column(name = "_id")
        private Long id;

        public Long get_id() {
            return id;
        }
    
        public void set_id(Long _id) {
            this.id = _id;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name == null ? null : name.trim();
        }
    
        public String getPassword() {
            return password;
        }
    
        public void setPassword(String password) {
            this.password = password == null ? null : password.trim();
        }
    
        public String getMobile() {
            return mobile;

            this.session_key = session_key == null ? null : session_key.trim();
        }
    }
    
    3.2 项目一般会有同一的数据返回格式,这里我定义一个统一的返回对象为BaseResponse,代码如下,里面加入了swagger的描述
    package com.noah.contacts.bean;
    
    import io.swagger.annotations.ApiModel;
    import io.swagger.annotations.ApiModelProperty;
    
    @ApiModel(value = "通用返回对象" , description = "BaseResponse<T> 为返回的具体的数据对象")
    public class BaseResponse <T>{
        @ApiModelProperty(value = "成功或异常标志位,1为成功,0为异常",dataType = "Integer",required = true)
        private int result;
        @ApiModelProperty(value = "描述",dataType = "String",required = true)
        private String msg;
        @ApiModelProperty
        private T data;
    
        public int getResult() {
            return result;
        }
    
        public void setResult(int result) {
            this.result = result;
        }
    
        public String getMsg() {
            return msg;
        }
    
        public void setMsg(String msg) {
            this.msg = msg;
        }
    
        public T getData() {
            return data;
        }
    
        public void setData(T data) {
            this.data = data;
        }
    }
    
    3.3 删除bean下除了User和BaseResponse外的mybatis-generator-maven-plugin插件生成的其他文件,删除mapper下的文件,修改dao下的UserDao.java如下:
    package com.noah.contacts.dao;
    
    import com.noah.contacts.bean.User;
    
    import tk.mybatis.mapper.common.Mapper;
    
    public interface UserDao extends Mapper<User> {
    
    }
    
    3.4 增加UserController.java,IUserService.java,Userservice.java
    package com.noah.contacts.controller;
    
    import com.noah.contacts.bean.BaseResponse;
    import com.noah.contacts.bean.User;

    public class UserContorller {
    
        @Resource
        private IUserService userService;
    
        @ResponseBody
        @RequestMapping(value = "/doLogin", method = RequestMethod.POST)
        @ApiOperation(value = "登录", notes = "获取用户信息", httpMethod = "POST")
        @ApiImplicitParams({
                @ApiImplicitParam(paramType = "query", name = "username", value = "用户名", required = true, dataType = "String"),
                @ApiImplicitParam(paramType = "query", name = "password", value = "密码", required = true, dataType = "String")})
        public BaseResponse<User> doLogin(@RequestParam("username") String username, @RequestParam("password") String password) throws Exception {
            BaseResponse<User> response = new BaseResponse<User>();
            response.setResult(1);
            response.setMsg("登录成功");
            User user = userService.doLogin(username, password);
            response.setData(user);
            return response;
        }
    
    }
    
    package com.noah.contacts.service;
    
    import com.noah.contacts.bean.User;
    
    public interface IUserService {
        public User doLogin(String name, String password);
    }
    
    
    package com.noah.contacts.service;
    
    import com.noah.contacts.bean.User;
    import com.noah.contacts.dao.UserDao;
    import org.springframework.stereotype.Service;
    
    import javax.annotation.Resource;
    
    @Service("IUserService")
    public class UserService implements IUserService{
    
        @Resource
        UserDao userMapper;
    
        public User doLogin(String name, String password) {
            User selectUser = new User();
            selectUser.setName(name);
            selectUser.setPassword(password);
            User result = userMapper.selectOne(selectUser);
            return result;
        }
    }
    

    到这里就可以调用接口测试了,运行项目后,在浏览器输入http://localhost:8080/swagger-ui.html
