SpringMVC开发移动端接口（返回Json数据）

来源：互联网发布：对p2p网络信贷的看法编辑：程序博客网时间：2024/05/18 00:44

Eclipse+Spring+SpringMVC+Redis+MySql

+MyByties+Maven开发移动端接口

1、pom.xml文件，配置Maven本地仓库

pom文件是Maven的配置文件，可以加载依赖的jar。还可以加载本地的jar。打包项目等。
说明：

1、本项目要用MVC返回json数据，除了要在controler中的对应方法上添加 @ResponseBody，来说明是返回特殊类型数据（非页面）外，还要引入com.fasterxml.jackson.core的jar包。具体可以参考下边的代码。
2、本项目除了Maven管理和下载的jar包外，还有本地class路径下的lib目录里的本地jar包需要引用。用Maven打包管理项目，需要在pom文件中配置好本地jar。否则打包不成功。
如：

<dependency>    <groupId>org.springside</groupId>    <artifactId>springside3-core</artifactId>    <version>3.3.4</version>    <scope>system</scope>      <systemPath>${project.basedir}/lib/springside3-core-3.3.4.jar</systemPath>   </dependency>

pom.xml配置如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

3、配置Maven的本地仓库

Maven本地仓库window系统下默认是 C:\Users\Administrator.m2\repository 这样的路径下。但因为C盘的重装系统等的原因，有时需要更改本地仓库路径。

设置本地maven仓库方法如下:
1、建立本地文件夹，做为仓库本地地址。如：D:\maven_local\repository

2、设置maven配置文件，：settings.xml。并将该文件复制到仓库目录下边。如：D:\maven_local 这里配置了国内镜像，是阿里云的。速度我很满意。感谢马云粑粑。

<?xml version="1.0" encoding="UTF-8"?><settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0           http://maven.apache.org/xsd/settings-1.0.0.xsd"><localRepository>D:\maven_local\repository</localRepository><mirrors><mirror>        <id>nexus-aliyun</id>        <mirrorOf>*</mirrorOf>        <name>Nexus aliyun</name>        <url>http://maven.aliyun.com/nexus/content/groups/public</url>    </mirror></mirrors></settings>

3、设置eclipse的maven的插件对应的setting文件。
eclipse点击windows->preferences->maven->User setting下
修改user setting选项为：D:\maven_local\settings.xml，并点击update settings。
并点击下面的reindex按钮更新索引

4 这里该项目打包成war包是ROOT.war。本意是访问接口的时候不带工程名。将ROOT.war放到Tomcat路径下，自动解析，即可访问。如果是在Eclipse中debug或直接调试布置，需要更改Tomcat的虚拟路径。下边两个方法都可以达到这个目的。

2、配置web.xml 和 SpringMVC

web.xml需要配置SpringMVC的监听器，加载spring的xml配置文件，配置springmvc DispatcherServlet ，和需要拦截的url等。废话不说了，直接上代码

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">  <display-name>KeegooDService</display-name>  <!-- 监听spring上下文容器 -->    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>  <!-- 加载数据字典  在Spring配置的下面-->  <listener>    <listener-class>com.keegoo.cache.InitDicListener</listener-class>  </listener>  <!-- 加载spring的xml配置文件到spring的上下文容器中 -->    <context-param>          <param-name>contextConfigLocation</param-name>          <param-value>classpath*:/spring-mvc.xml</param-value>    </context-param>    <!-- 配置springmvc DispatcherServlet  -->    <servlet>      <servlet-name>applicationContext</servlet-name>      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>      <init-param>          <param-name>contextConfigLocation</param-name>          <param-value>classpath*:/spring-mvc.xml</param-value>      </init-param>      <load-on-startup>1</load-on-startup>    </servlet>    <!-- 配置DispatcherServlet需要拦截的url -->    <servlet-mapping>      <servlet-name>applicationContext</servlet-name>      <url-pattern>/</url-pattern>    </servlet-mapping>   <!-- Filter 定义 Character Encoding filter -->    <filter>        <filter-name>encodingFilter</filter-name>        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>        <init-param>            <param-name>encoding</param-name>            <param-value>UTF-8</param-value>        </init-param>        <init-param>            <param-name>forceEncoding</param-name>            <param-value>true</param-value>        </init-param>    </filter>    <!-- Filter 映射 -->    <filter-mapping>        <filter-name>encodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping></web-app>

这里需要加载classpath*:/spring-mvc.xml
spring-mvc.xml代码如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

这里又用到了Redis和数据库访问是配置文件classpath*:/application.properties

application.properties的代码如下

#jms#jms.brokerURL=tcp\://10.171.43.136\:61616?wireFormat.maxInactivityDuration\=0jms.brokerURL=tcp\://127.0.0.1\:61616?wireFormat.maxInactivityDuration\=0#1(\u56fd\u90fd);2(\u4f0a\u7f8e);3(\u901a\u8fbe)smsChannelTrigger=3#mysqlconnection.driver=com.mysql.jdbc.Driverconnection.url=jdbc:mysql://localhost:3306/keegoo?useUnicode=true&characterEncoding=utf8connection.username=rootconnection.password=123456#connection.url=jdbc:mysql://101.200.113.76:3306/kee61?autoReconnect=true&amp;characterEncoding=utf8#connection.username=kgtest#connection.password=JG2016dev!connection.initialSize=10connection.maxActive=100connection.maxIdle=30connection.minIdle=5connection.maxWait=5000connection.removeAbandoned=trueconnection.removeAbandonedTimeout=3000connection.logAbandoned=false#redis的服务器地址redis.host=127.0.0.1#redis的服务端口redis.port=6379#密码#redis.password=#链接数据库redis.default.db=0#客户端超时时间单位是毫秒redis.timeout=10000#最大连接数redis.maxActive=300#最大空闲数redis.maxIdle=100#最大建立连接等待时间redis.maxWait=1000#isdev=ture表示开发环境，isdev=false表示生产环境isdev=true

3、Redis

本项目需要安装和开启Redis。
可参考 http://www.runoob.com/redis/redis-tutorial.html
这里只上几张截图即可。
用到的cmd命令为：

1.打开一个 cmd 窗口使用cd命令切换目录到 C:\redis（你下载解压的目录即可）
运行 redis-server.exe redis.windows.conf
2.切换到redis目录下运行 redis-cli.exe -h 127.0.0.1 -p 6379 。
设置键值对 set myKey abc
取出键值对 get myKey

下边直接上截图

这里写图片描述
