my project has parent , 3 modules, 1 of childs web project.

my configuration following:

• in parent pom:

  <parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>1.5.2.release</version> </parent> ... <properties> <springboot.version>1.5.2.release</springboot.version> </properties> ...

  </dependencymanagement> <dependencies> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-web</artifactid> <version>${springboot.version}</version> </dependency>
<dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-tomcat</artifactid>
<version>${springboot.version}</version> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-legacy</artifactid> <version>1.1.0.release</version> </dependency> </dependencies> </dependencymanagement>

-in web child pom:

`   <dependencies>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-web</artifactid>     </dependency>     <dependency>         <groupid>org.apache.tomcat.embed</groupid>         <artifactid>tomcat-embed-jasper</artifactid>         <scope>provided</scope>     </dependency>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-security</artifactid>     </dependency>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-legacy</artifactid>     </dependency> </dependencies> ` ... ` <plugins>    <plugin>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-maven-plugin</artifactid>    </plugin> </plugins> `    

• in web.xml: <listener>
<listener-class>org.springframework.boot.legacy.context.web.springbootcontextloaderlistener</listener-class> </listener>

spring-boot-legacy, 1.1.0.release guaranteed work spring boot, 1.4.2.release.

not works in usual spring boot work. programatically defined servlet filters , servlets (e.g. using filterregistrationbean or servletregistrationbean) not work, think due limitations in servlet 2.5. servlet 3.0 annotations not work either (e.g. @webservlet)

tomcat 6 supports servlet 2.5. spring boot legacy app should work fine using like:

mvn tomcat6:run

<plugin>   <artifactid>tomcat6-maven-plugin</artifactid>   <groupid>org.apache.tomcat.maven</groupid>   <version>2.0</version> </plugin> 

also important give springbootcontextloaderlistener clue find "application" class (the class containing @springbootapplication), e.g.:

your web.xml contain like:

<context-param>     <param-name>contextconfiglocation</param-name>     <param-value>demo.application</param-value> </context-param> 

once understand limitations, amazing work!
