## 1. 引入pom依赖 ##

<?xml version="1.0" encoding="UTF-8"?>
    <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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
    
      <groupId>com.zjw</groupId>
      <artifactId>spring-boot-study</artifactId>
      <version>1.0-SNAPSHOT</version>
    
      <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.16.RELEASE</version>
      </parent>
    
      <dependencies>
        <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
      </dependencies>
    </project>

## 2. 引入配置文件 ##

### 2.1 引入application.yml ###

spring:
      application:
        name: spring-boot-study
    server:
      port: 10000

### 2.2 引入logback.xml ###

<?xml version="1.0" encoding="UTF-8" ?>
    <configuration>
      
      <property name="LOG_HOME" value="./log"/>
      
      <property name="LOG_NAME" value="spring-boot-study"/>
      
      <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
          
          <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
        </encoder>
      </appender>
      
      <appender name="ROLLING_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
          
          <FileNamePattern>${LOG_HOME}/${LOG_NAME}-%d{yyyy-MM-dd}.log
          </FileNamePattern>
          
          <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
          
          <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
        </encoder>
        
        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
          <MaxFileSize>10MB</MaxFileSize>
        </triggeringPolicy>
      </appender>
      
      <root level="INFO">
        <appender-ref ref="STDOUT"/>
        <appender-ref ref="ROLLING_FILE"/>
      </root>
    </configuration>

## 3 编写启动类和Controller类 ##

### 3.1 启动类 ###

package com.zjw; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class MyApplication { private static final Logger logger = LoggerFactory.getLogger(MyApplication.class); public static void main(String[] args) { SpringApplication.run(MyApplication.class, args); logger.info("Spring Application Running..."); } }

### 3.2 Controller类 ###

package com.zjw.controller; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class HelloController { private static final Logger logger = LoggerFactory.getLogger(HelloController.class); @RequestMapping("/hello") public String hello() { logger.info("HelloController hello function invoked."); return "Hello, I'm Spring boot Application."; } }

## 4 编写测试类 ##

package com.zjw.test; import static org.hamcrest.Matchers.*; import static org.junit.Assert.*; import java.net.MalformedURLException; import java.net.URL; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.context.embedded.LocalServerPort; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.boot.test.context.SpringBootTest.WebEnvironment; import org.springframework.boot.test.web.client.TestRestTemplate; import org.springframework.http.ResponseEntity; import org.springframework.test.context.junit4.SpringRunner; @RunWith(SpringRunner.class) @SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT) public class HelloControllerTest { private static final Logger logger = LoggerFactory.getLogger(HelloControllerTest.class); @LocalServerPort private int port; private URL base; @Autowired private TestRestTemplate template; @Before public void before() throws MalformedURLException { this.base = new URL("http://localhost:" + port + "/hello"); } @Test public void testHello() { ResponseEntity<String> response = template.getForEntity(base.toString(), String.class); logger.info(response.getBody()); assertThat(response.getBody(), equalTo("Hello, I'm Spring boot Application.")); } }
