简单之美，springmvc，mybatis就是一个很好的简单集成方案，能够满足一般的项目需求。闲暇时间把项目配置文件共享出来，供大家参看：
1.首先我们来看下依赖的pom：
1 <!-- spring --> 2 <dependency> 3 <groupId>org.springframework</groupId> 4 <artifactId>spring-core</artifactId> 5 <version>${spring.version}</version> 6 </dependency> 7 8 <dependency> 9 <groupId>org.springframework</groupId> 10 <artifactId>spring-beans</artifactId> 11 <version>${spring.version}</version> 12 </dependency> 13 14 <dependency> 15 <groupId>org.springframework</groupId> 16 <artifactId>spring-context</artifactId> 17 <version>${spring.version}</version> 18 </dependency> 19 20 <dependency> 21 <groupId>org.springframework</groupId> 22 <artifactId>spring-tx</artifactId> 23 <version>${spring.version}</version> 24 </dependency> 25 26 <dependency> 27 <groupId>org.springframework</groupId> 28 <artifactId>spring-web</artifactId> 29 <version>${spring.version}</version> 30 </dependency> 31 32 <dependency> 33 <groupId>org.springframework</groupId> 34 <artifactId>spring-webmvc</artifactId> 35 <version>${spring.version}</version> 36 </dependency> 37 38 <dependency> 39 <groupId>org.springframework</groupId> 40 <artifactId>spring-jdbc</artifactId> 41 <version>${spring.version}</version> 42 </dependency> 43 44 <dependency> 45 <groupId>org.springframework</groupId> 46 <artifactId>spring-test</artifactId> 47 <version>${spring.version}</version> 48 <scope>test</scope> 49 </dependency> 50 51 <!-- mybatis 包 --> 52 <dependency> 53 <groupId>org.mybatis</groupId> 54 <artifactId>mybatis</artifactId> 55 <version>3.2.8</version> 56 </dependency> 57 58 <!--mybatis spring 插件 --> 59 <dependency> 60 <groupId>org.mybatis</groupId> 61 <artifactId>mybatis-spring</artifactId> 62 <version>1.2.2</version> 63 </dependency> 64 65 <!-- mysql连接 --> 66 <dependency> 67 <groupId>mysql</groupId> 68 <artifactId>mysql-connector-java</artifactId> 69 <version>5.1.34</version> 70 </dependency> 71 72 <!-- 数据源 --> 73 <dependency> 74 <groupId>com.alibaba</groupId> 75 <artifactId>druid</artifactId> 76 <version>1.0.12</version> 77 </dependency> 78 79 <dependency> 80 <groupId>org.aspectj</groupId> 81 <artifactId>aspectjweaver</artifactId> 82 <version>1.8.4</version> 83 </dependency> 84 85 <!-- log4j --> 86 <dependency> 87 <groupId>log4j</groupId> 88 <artifactId>log4j</artifactId> 89 <version>1.2.17</version> 90 </dependency> 91 92 <!-- servlet --> 93 <dependency> 94 <groupId>javax.servlet</groupId> 95 <artifactId>servlet-api</artifactId> 96 <version>3.0-alpha-1</version> 97 </dependency> 98 99 <dependency> 100 <groupId>javax.servlet</groupId> 101 <artifactId>jstl</artifactId> 102 <version>1.2</version> 103 </dependency> 104 105 <!-- json --> 106 <dependency> 107 <groupId>org.codehaus.jackson</groupId> 108 <artifactId>jackson-mapper-asl</artifactId> 109 <version>1.9.13</version> 110 </dependency> 111 112 <dependency> 113 <groupId>com.alibaba</groupId> 114 <artifactId>fastjson</artifactId> 115 <version>1.2.3</version> 116 </dependency> 117 118 <dependency> 119 <groupId>com.fasterxml.jackson.core</groupId> 120 <artifactId>jackson-annotations</artifactId> 121 <version>${jackson.version}</version> 122 </dependency> 123 124 <dependency> 125 <groupId>com.fasterxml.jackson.core</groupId> 126 <artifactId>jackson-core</artifactId> 127 <version>${jackson.version}</version> 128 </dependency> 129 130 <dependency> 131 <groupId>com.fasterxml.jackson.core</groupId> 132 <artifactId>jackson-databind</artifactId> 133 <version>${jackson.version}</version> 134 </dependency> 135 <!-- 文件上传 --> 136 <dependency> 137 <groupId>commons-io</groupId> 138 <artifactId>commons-io</artifactId> 139 <version>2.4</version> 140 </dependency> 141 142 <dependency> 143 <groupId>commons-fileupload</groupId> 144 <artifactId>commons-fileupload</artifactId> 145 <version>1.2.2</version> 146 </dependency>
spring 选用的是4.1.4的版本，根据系统需要我们可以选择自己适合的版本。
2.相关的配置文件：

使用了druid的数据源，在web中的详细配置可以参看代码。
